I'm sure I have it, but never went to have it diagnosed. I started taking St. John's Wort 3x a day which helps me a lot, all of the negativity and ideas just don't hang around as easily. I used to hold onto stuff and it would eat away at me, but now I experience it, and it goes away.
I got through it before the St. John's Wort by staying busy (schoolwork and games) but if I ever had time to think about myself it would always get progressively worse. I got through the day by telling myself that I would like to live long enough to be happy, and feel free, and that I at least deserved that much before I did anything stupid (stupid to everyone else, not stupid to me at the time.) I'm glad now, because I feel that I "made it out" and became a stronger person because of it.
It was pretty bad, I was suicidal, and every problem I had just felt that it could be solved most easily by killing myself. I would cross streets with my eyes closed everyday, and cry every night. I made plans on how to kill myself without anyone noticing, and how to do it at a time when, if anyone noticed, it would be too late. This went on for some years, with falling asleep usually letting me let go of how I felt, and I could start the next day just regularly depressed, and not suicidal. I decided that I needed help when I woke up, and I was still suicidal.
But yeah~ things are better now. I have everyday worries, not-so-everyday worries, but they don't get me down as much as they used to. I still take the St. John's Wort 3x a day, and regular exercise makes me feel good. I stay busy with work and nursing stuff so I feel like, if I have a bad day (for whatever reason), I'm still making money and educating myself to be the person I want to be. As long as I'm feeling like I have progress going on somewhere in the background, I have something to make me feel "accomplished" all the time. I have my days (...or sometimes weeks :x) where things aren't feeling right and I feel like I'm not in control, so I force myself to do something (usually the treadmill) that makes me feel good about myself.
I still don't think I'm the happiest I can be, or live the most exciting, fun-filled life, but I think I'm getting by for now. I think I'm one of those self-improvement people lol
