Hi Jess, good questions to have asked. I had wondered these things myself. Strangely enough, my inner crew Jesse is the one who is into the S.I. stuff, I guess. I just know we occasionally cut and scratch a lot. I find ourselves biting lately. I know we tried the ice methods, markers, and have taken up physical exercise as means of coping. Journaling does help too, but that gets hard when I am co-con or median with my inner crew people. I know for our crew it has been a basis of being trauma based yes, as we didn't know any other alternatives, yet it's also something that is mutually shared with all of us, as we know it's gonna happen regardless of how much we beg for it not too. We can discuss options and hope for the best but at times, it's hard to control it. I'm not sure on if self harm and multiplicity has no intrinsic connection, so I will leave that question up to others who best know. Again, I don't speak for anyone except what we, in my crew, agree on. So, if what we said or do, doesn't agree with anyone, sorry, but we're speaking for ourselves only. Hope no one minds. We did like the questions though.
