Anxiety Insomniac

In the period of the last 7 hours I have had 4 different trips to my bathroom to cut. That is ridiculous. I'm beyond tired, high on painkillers/sleeping aids, can't stop my constant anxiety attacks, & I my legs are sore.
I have a therapy appointment in five hours.... I'm wondering if I should go. My anxiety is so bad.... All I've been doing is stuffing my face & cutcutcutcutting. :|
I've completely stopped going to school, haven't even had an attempt at my make-up homework. That damn fact might get me sent back to placement.... that in itself skyrockets my anxiety. FML!
