Firstly, I'm not insane or anything. I have chronic depression and very negative self-esteem. I was talking to her over facebook, so she didn't see me have a flip out. I actually have quite a few friends, but since finishing high school last year everyone is so busy working or at university that we rarely have any time to hang out. I had three friends in high school who I was especially close to and two of them pretty much shut me off. For about a year now every time I've asked them to hang out they've said no, one of the blatantly lies about being busy or tired because she just can't be bothered. The other one, the one I asked, has moved out of home and has been struggling to pay rent and bills, so she's been working lots. I'm so used to hearing them say no, that when she said yes it shocked me and I didn't know how to react - hence triggering the panic attack. Once I'd calmed down I was excited and we're going to have lunch on Monday :)
