Could this be worse?

So, I have a problem. I'm a former cutter and I havn't cut since like april. I used to be able to hide my emotions.. better. Since I've stopped cutting, I've felt more hostile than usual and I am having more urges to harm people who are getting on my nevers. I think this may be becuase I've stoped cutting, I have nothing to take my feelings out on. I'm not really sure, but I need to find a better way to mange my anger because I'm scared of actualy hurting someone or going back to cutting. I feel really out of control.
