what a difficult situation for you. i think the best route is for you to seek professional advice from a t for him. some cutters do not always have conscious awareness of what they do in regards to their cutting, i think there is some dissociation.

i have si-ed my face, it is a pretty harsh thing to do, even by si-ers standards, if that makes sense - i guess you just need to be there to help him, it sounds like you're doing a brilliant job already. i hope you manage to get some assistance good luck xxxxxx
