I'm 19.

I'm really sorry about your friend but I don't think that the PMT could have worsened her conditions... I mean, it's just a thread. Depression is not funny and I know it for experience, sadly. As I already told you, I don't know the difference. If you want to explain to me, I'll listen, because right now I can only tell you that those girls are funny and nice (my opinion towards them won't change, though)
