I've been diagnosed with bipolarism, and my symptoms are much, much worse than my mother's ever were - I have bouts of serious depression from time to time, and I've screwed up a lot because of it.
It mostly started when my friend passed away back in 2008, that was just the start of things going downhill. I started slacking off in school, I didn't care. I got into drinking a lot, partying all the time - but I started to break away from it. My aunt passed away in late 2009, and I backtracked - I started with the drinking again, I really started slacking off in school, nearly ruined my whole life. But then I started making more positive changes, too - I wasn't as rude, I wasn't as selfish, I tried to be more open minded. Along with those changes, my whole lifestyle changed.
This past year, I managed to get out of the drinking for a while - I pulled up my marks, held up my job in the meantime, and all it took was for me to be a nicer person. It made people happier, I got to see the smiles that I had caused - that was enough for me. In June this year, I met a girl who I thought was fantastic, we were seeing each other, we dated... she slowly got me back into drinking and very minor drugs - but when we split up, I took a turn for the worst again. Severe depression, two months straight where I would go to work every day, come home, go out and get wasted, get as high as I could, go home and pass out. My friends realized the changes I was making again, gave me a reality check. I turned more to the music I love, my closest friends, and tried to settle my life a bit.
The past two months, I've been sleeping maybe an hour or two every night, even though I'm up at 5:30AM every weekday for work - I'm up in case someone needs someone to talk to, someone to give them advice. In the past two months, I've made so many people happier, and I've been happier. I'm dating the sweetest girl I've ever met to make things even better - when I can't take my own problems on top of all the problems of my friends, she's always there for me.
When I was unhappy, I'd turn to substances. Light drugs, hard drugs, heavy drinking - it was disgusting, but it made me forget. But I've broken the habit - I still drink occasionally, but I know and respect my limits, but I use the happiness I can give OTHERS to fuel my own happiness. I can do right by a handful of people, and maybe they'll follow my example and do right by another few handfuls - I'd be happy to be the cause of those smiles.
