I don't think the problem is with either cutting or masturbation. Cutting/masturbation are what you are using as coping mechanisms for dealing with a deeper rooted problem. That problem could be related to previous trauma or abuse. It could be related to interactions you have had (or are still having) with family members, friends, or others. If you don't feel like you can talk with a counselor or your bishop, could you talk to one of your young woman's leaders or anyone else? Talking on a forum can be helpful, but you also need to talk with someone in person, someone who loves you and with whom you can trust.

I am not going to answer which is worse but I will say that there are healthier means of coping that don't involve cutting or masturbation. Counseling can help you identify what the actual problem might be. A counselor, bishop, young woman's leader, etc. might be able to help you identify other possible solutions and coping mechanisms for this problem.
