Hi so I'm 19 and have been working as a waitress over the summer before I go back to uni. It's been good up until the last week. I seem to have randomly developed a fear of going into work. I work long hours (some shifts are 12+ hours) and when I start work in the morning the idea of not being able to leave until midnight really freaks me out. I've gone in on two separate days and had to leave due yo panic attacks/uncontrollable crying that comes out of nowhere.

 While I'm working I just have this deep feeling of dread like something awful has happened or that I've done something horrible. My anxiety is centered around being trapped there and anxious and not being able able leave. Once I'm at home I'm completely fine and almost feel like I've just made it up. I feel pretty useless that I can't cope with everyday life without breaking down and crying infront of my peers.I've struggled with OCD/GAD my whole life but it's not usually focused around one situation and it's been a while since it's been this bad. Should mention I'm on venlafaxine 75mg for depression/cyclothymia and that seems to work ok for my anxiety aswell.

I've been a day off and I'm not scheduled to work off until Tuesday from 10:30am- 12am and I am absolutely dreading it. I just genuinely feel like I cannot cope with it. It's not the job because I'm very friendly with the people I work with and get on really well. I know what to do and how to do it, it's just this overwhelming anxiety I get when I'm there that I can't deal with. Anyways any advice/opinions welcome, thanks in advance :)
