Yeah I am not sure. I've just been trying to identify them without asking. SI means self injury I think.

Not sure what SUI or LCM is

Not really sure what PDOC is either. i was thinking like psych doc or something. Wish people would just take the extra second to write these out since I find pretty much all of them silly sounding. Especially when shortening therapist to just "T"? I get such an image in my head when people use T to refer to their therapist.
