Sometimes we SI too because there were times that we were emotionally so scarred that we couldn't speak the words that hurt us so bad emotionally...Sometimes it's so bad that we are so numb to the feelings we need to express that just seeing the blood the cut's the artificial pain I say artificial because most of us don't feel pain when we cut, because were so numb that we need to see the blood the scar's the skin open the flesh to know were ALIVE....I know that's the case for me...I only just now after just now going into starting my 4th year of therapy did I now realize with my arms I might have said sorry if I did, however why I use them as a tool, but sometimes I do it just because not even a reason......Just like you mentioned...I don't even feel triggered? Or so I don't think I am? However our mind is working overtime allot of time!!! That's why if we have issues like these having a therapist is so important...Someone that's not emotional in our lives, NOT SAYING at all that your good friend is NOT doing you justice...However someone that can see beyond what were saying, knows what were really saying because there trained is really beneficial? Just a suggestion....Take care and biggest hugs and I so relate so your NOT ALONE,
