I think you're misinterpreting depression. Depression is more of a void than it is "feeling very sad". With depression, there's no room for sadness. It's a lack of feeling, a sort of cold numbness. Given the inexplicable whirl of emotions you're feeling, I'm more inclined to think your emotions are more inclined to be interpreted as hormonal. It's a result of adolescence and is to be expected.

You can stay; just tone down the theatrics a bit. I'm personally not a big fan of the "deliberate refusal to cooperate" jokes exhibited on the last page, but that's just me and [i]my[/i] cup of tea. I can't speak for anyone else here.

I also want to add that I, too, have suffered sexual abuse - but I offer no excuses.
