I've have depression and it spirals in and out of control. I've learned to control it over time. I'm 18, it was at its worst when I was around 14-15. I've also had suicidal thoughts, but thankfully those have gone away in recent years. I've always come from a good background family wise, so environment never had a part in my depression. My parents were always very supportive of me. My dad has depression too, so I guess it runs in the family. I don't take meds for it anymore, so hopefully I'm starting to conquer it. If anyone has depression and needs someone to talk to, please add me on facebook. I know what you're going through. Props Steve on the thread.
