<s>[INST] I completely rip off a toe nail for no reason. I have been doing this since I was a teenager. I think it lets me concentrate on the pain of it, I am not sure. I had a bad life but have turned it around with help from many . I did this again the other day while away on vacation out of the blue and can t figure out why or how to stop. Any input is greatly appreciated . [/INST] Hello, glad to help you. Ripping off toenails is quite painful. As you mentioned you do this frequently without any obvious reason. Doing so help you concentrate. I believe that you seek pleasure while doing so. You might have this anomaly where people get pleasure by giving pain to themselves, torturing or hurting ones own body.I would suggest you to seek a consultation from a shrink (psychiatrist) asap, because if It's so, it's just the beginning and can be dealt easily. </s>
