Why don't you go and see a real person...is there a valid physical reason (maybe there is I don't know)  but i do know that computers are actually part of the problem...real life is about real people...looking them in the eye..revealing your pain....eye to eye..
A good psychologist (if you can find one) who is experienced in self harm issues can be very useful...I stress not just any psychologist...but one who is specifically trained in self harm issues...ask questions before you book....Mike
