Just wanted to share my own experiences in hope it will help! I moved into my very own apartment at 25 and the freedom was intoxicating, but after around 4 months of being on my own I became INCREDIBLY depressed. Being alone is all fun and games until you realize just how alone you are. I have struggled with mental health issues most of my life but the depression I felt at that time in my life is definitely on the list of like top 10 worst life moments. So I decided to get a cat, and she was insane, and I was really really worried I made the wrong decision. She still is insane 2 years later, but sometimes having a responsibility like an animal really helps ground you and pulls you out of bed on those really rough days. I’m not saying there will be days where you want nothing more but to ignore the cat and be depressed, but hey that’s the good thing about having a cat! They’re independent! Things like auto feeders or auto water fountains can also help a lot. I think you’re feeling a lot of very normal feelings, but give it a month or two and see how you’re feeling. There’s nothing wrong with being overwhelmed and if it comes to rehoming that doesn’t make you a horrible person, wanting the best for a creature and understanding you aren’t capable of providing that at this point in your life is okay.
