I had a nervous breakdown at 13; which I later found out had happened to my father and great grandfather at around the same age. I became terribly, terribly depressed and couldn't function at all really. I ended up leaving school, though I tried to go back several times until I was about 19 and just realised it wasn't going to happen the way I was going. I would fall into a cycle of severe anxiety followed by depression when things fell apart because the anxiety overwhelmed me.
At eighteen I moved out and got a job and a place. But the job was stressfull and couldn't really cover my bills; also it was customer service which didn't help my anxiety any. I was good at it(I sold 3 of my store's premotional cards in one shift before my break, something which hadn't been done at my store before.) but the constant feeling of trying to please people would trigger anxiety attacks and the stress around work caused me to miss too many shifts so they let me go. I spent the rest of that year sleeping, going to therepy and trying to scrape together enough cash to pay my rent, though in truth my mom was pretty much keeping me a-float.
I'd been in therepy on and off since I was 14, it had helped but it took a long time before I realised I was messed up and I was going to have to deal with that, instead of just trying to make it go away. I'd been on meds but they didn't really fix anything they just made me numb, which became a problem later when I was trying to figure out where this was all coming from.
After that year I moved back home, I went to therepy for a while longer and I still check in every couple of months. I don't take pills anymore and I haven't had an anxiety attack in years, I still get depressed but it runs it's course intstead of taking over my life. I haven't had much luck in finding jobs, not finishing highscool has that effect. But I just keep trying, that's all I can do and though It feels like it's taking forever sometimes, things are getting better.
Sorry this was so long a post, thanks for reading.
