Yeah, I struggle all the time with SI and with carrying around razors in my purse and car. T hates this b/c he stated one time he would feel awful if I SI after a session - like he would feel responsible in some way. So a lot of the time I don't tell him they're there. I do, however, tell him whenever I SI. Then we talk about what caused it. Little by little this has helped to decrease the frequency of SI. So, bottom line, I would try to talk to your T if you can.
