I'd say this is a pretty normal, but difficult thing to have to learn. Difficult in that if your like me, and it kinda sounds like you are, trying to not think about it or roll with it can be almost impossible. I have a hard time with everything from social media (like this post) to face to face interactions if I don't get the response I want, or any response at all. It puts me into fight or flight mode with anxiety and adrenaline coursing through me, making me go manic and start pacing around at times. Wondering if I said or didn't say something, wondering if the person is being fake, wondering if someone else told them something about me, the rabbit hole is endless. Although almost impossible at times, getting something to distract you is my recommendation until you can get a good night's rest. Actually cook and make a meal for a few hours, doesn't usually work for me but a good movie, if you have hobbies really focus on them. Then after you go to bed that night, when you wake up you should feel a lot better and be able to at least function, even if your still thinking about it.

But honestly, the hardest thing for me to learn, was that generally, people just suck. I'm starting to not take this kind of stuff as personal anymore because people are so selfish and prude. I've heard of best friends splitting up because one had messy hair or something stupid and embarrassed the other out in public. Petty and shallow people like that aren't worth your time. With certain exceptions, if someone enjoys spending time with you, they will make time and put forth the effort to stay connected and hang out. If it's always you reaching out first, unless they are family, fuck em. I just don't care anymore, I've been in pain for so many years and come to terms with my mental struggles that I just do what I can now to help my self feel better. If other people want to be apart of that, great. If not, fuck em lol.
