What kind of help can I get?!

I have a few problems starting with the fact I feel completely unstable. I constantly feel like crying, I self harm anyway but it's got to the point I'm doing it in staff toilets at work with whatever I can find (e.g- paperclip) I don't want to die but I can't stop feeling like I should just end everything. I can't sleep and I'm only eating liquid foods. If I eat anything solid I either chew and spit or make myself sick and I usually burn twice the calories I consume on my exercise bike. I have been seeing a counsellor for a while but it seems to just make me feel worse and selfish for putting my problems on her. I just can't stop thinking about ending everything. I'd really appreciate it if anyone could give me any advice on how to make things any better?
