I can't last a day

I relapsed after 2 months, having really hard time to stop or talk about it. they are not deep or something like that, so they are not dangerous but I know that it will go worse day by day as I get close to taking the university entrance exam. I was expecting to relapse but not this soon. I'm just so sick of being this alone and I'm angry that the only warmth i feel is the blood covering my leg.
