It's really hard to say, as I've never been officially diagnosed with anything. I've always just kind of had an idea of what's happening with me, and only recently started even trying to set any sort of treatment process in to motion.

In high school, somewhere around grade 9, I started pretending to be 'sick' on days that I just couldn't handle going to school/even being awake. I slept through so much of my life at that point.
I don't know why- I wasn't really bullied, people apparently really liked me (I really thought every hated me, though.), and I had friends (but usually was too uncomfortable to be around them).
I just... never really stopped doing that throughout school. I didn't graduate because of that.

I self-harmed for a few years between 15-17, and ended up hospitalized after a cry-for-help suicide attempt at 16.

I don't remember a time when I wasn't sort of 'sad' to some extent. It's just always been that way.

I've been spending a lot of time thinking over things and trying to gather my thoughts before I go see anyone, but am also worried I might over-think and end up imagining things that where never there to begin with, if that makes sense.
