AIO for wanting to cut off friends for not being present in my life?
I (28M) have had a pretty rough time over the last few years. Last year, I attempted to take my own life, and due to a mishap, not only did I fail, but I accidentally gave myself a concussion. I went to the hospital and got it checked out and I made a full recovery, but none of my closest friends seemed to be even slightly concerned, even though I was entirely honest with them as to what gave me the concussion in the first place. It really bothered me, and nobody made any effort to even check on me in the months after. I didn't want to just cut them off, because I've known all these people for going on 7 years. I decided that I'd give it time and try to see if I'd change my mind later down the line.
Here we are, one year later. My birthday passed by recently and not a single call, not a single text, nothing. I had exactly one person message me on my birthday, and it was just one friend wanting to vent about something that happened to them--it wasn't something crazy, they just wanted to gossip about work. I spent an hour listening to them and then I jokingly mentioned it was my birthday and they just said "oh crap sorry lol anyways" and kept on going. This is a friend I've known since I was 14.
I want to just ghost everyone and start over, but I just moved to the other side of the US a couple years ago, and I haven't been able to make friends where I am because of trying to keep myself afloat in spite of everything. I'm worried I'll be alone, but at the same time I feel insane for trying to look the other way.
TLDR: My closest friends have not been present time after time and I'm considering ghosting them. Am I overthinking?
