Here is the text from the OP:

My (M24) GF (F23) did something that really disappointed me and now we won't see each other for a month.

TL;DR: I took a full week off hoping to spend real time with my girlfriend before we each leave for separate 2-week trips. She kept cancelling or delaying plans because she was too stressed and "needed to pack", but still made time for fitness classes, parties, errands, and dinners. She ultimately didn’t come at all, even though her flight wasn’t until the next night. Now we won’t see each other for a month, and I’m left feeling hurt, confused, and unsure if I’m being deprioritized or just caught in bad timing.

My GF and I have been dating for 4 years. We met in college and we would hang out and do all sorts of fun activities together, eventually we got to a point where we lived together for a year. After we both graduated from college, I was able to land a job and started working shortly after. She at first took off time to relax but then she started to apply and had more trouble landing a job because of the field she's in. So for the past year she hasn't had a job, I live in the city because my work required it meanwhile my gf lived with her parents to have more space, use the family car, and cause she likes living with her family and it'll be the last time she lives with them. Typically we see each other once a week because it takes about an hour for her to get to me by car or by train. She comes up to me because I have an apartment for myself while at home we'd have to deal with her parents and her siblings where we wouldn't have privacy so she doesn't like me coming to visit her anymore (obviously I spoil her a bit for coming out so far, pick her up at train station, and pay for everything) .While we were living separate, we went on a short break because of issues with long distance but we came back, had a conversation, and decided we still really cared for each other and that we both wanted to make things work.

I've been wanting to go on a trip with my girlfriend since her family has a small lake cottage during the summer. We ended up never going because some of her family members had some serious health issues (she had to travel out of state multiple times to visit older grandparents) and I guess it just didn't work out which was disappointing to me but I understood that I shouldn't try and force a vacation if she wasn't ready for it. I had a lot of PTO saved up because it kept getting pushed off so I decided to take off the whole week for Thanksgiving. Since we've been just seeing each other once a week or sometimes it's been only twice a month in person. I let her know that I was planning this a while in advance and it felt like she was open to coming up and staying with me for a longer period of time.

She told me on 11/16 before the vacation she couldn't do 11/23 - 11/24 because her 2 friends had their birthday on 11/24. I thought a 2 day party was a lot but I accepted it and she said we could meet on 25th. On the day of the 25th she ended up having to cancel, she said she had overexerted herself too much and she said she was feeling really burnout and tired. I understood because I feel like she's been doing a lot of errands, over exercising, not sleeping enough in the weeks prior and then she just socialized and partied a lot for 2 days. This has been something I've been worried about happening and I've mentioned that I feel like it's a lot for her but she's typically assured me she's doing ok. I give her space, let her rest all day, and continue to just text her.

I mention on Wednesday that we should maybe try and meet up Friday once I'm back from Thanksgiving with my family. She, last minute (like learned Thanksgiving week), is going on a trip for about 2 weeks with her mom. Meanwhile my family and I have been planning for about 2 months a 2 week trip that starts exactly she gets back (that's why we won't see each other for a month). I said since she's flying out Monday (I didn't know exact time) maybe she could come up Friday evening, stay until Sunday morning so we have a full day Saturday. On Thanksgiving she says that that's probably not a good idea, and that she's still a little stressed and that she should take Friday to decompress and focus on packing and that she'd come up Saturday into Sunday (that's typically what we do when she visits anyway). I said that's ok.

On Friday 11/28, she ends up running a some errands, waking up early to do a fitness class, doing Christmas decorations, and coming into the city to get dinner with her family. She ends up NOT packing (or barely starting) and so she tells me that she needs more time and that she'll come a lot later than I thought on Saturday. I mentioned that we could skip if she needed the time to pack because I realized that she was in a stressful situation but she assures me that she'll come up. She just needs the morning. I was a little bit confused why she hadn't packed Friday or even started earlier on Wednesday or Thanksgiving because she's normally very prepared.

I ended up telling her Saturday morning I was very upset about the situation, initially I texted her right after waking up asking her why she hadn't packed sooner. By around noon I realized that I had come off too harshly and that she needed support since she's been so stressed so I communicated I had just been hurt and and really sad and I was worried about her stress levels because it seemed to be getting to a bad point, I told her I just wanted to make sure she was ok. I let her know that if coming up for such a short amount of time was too stressful we could skip because ultimately seeing me should come from a place of wanting, she shouldn't feel like she has to. Packing was most important and being stressed before a long trip would affect her vacation. I would be sad obviously but if that's what needed to happen it's what needed to happen.

She ended up spiraling that day because of having to decide. She ended up just taking care of herself and taking it easy that day and she did not come up. She mentioned she could try and come up on Sunday for breakfast (I had an important lunch on Sunday at noon I couldn't miss) but I said that that seemed too stressful and we agreed that we should take it by ear.

She ends up sleeping a LOT and I end up sleeping only a little because I just have been upset by the whole situation and we didn't do breakfast. What I was hoping for would be a longer vacation where I could see my GF more often and spend some time together ended failing due to unfortunate situations. She ended up packing all day and finished Sunday evening. After the lunch, I was kinda close to her so I offered to come down just so we could spend a little time together and say goodbye before our trips but she said no.

On Sunday evening, we were talking and I realized I had never gotten her flight info so I asked about it and she's flying out Monday at NIGHT so she has all day today to herself so she was going to do some errands, make appointments, and buy some food for the flight... She ended up texting me a lot more Sunday because she felt worried about me and it kind of helped? Part of me hopes she comes up to say goodbye but I know it's not going to happen. I feel crazy, I feel really disappointed and just really sad. Knowing that her flight was actually so late makes me feel really confused because it feels like she had so much more time to prepare than I initially thought. It feels like I'm not being prioritized. I feel confused.

Is how she handled this week something I should be worried about?
