i honestly can't give a straight answer.

i agree with everything the op said- in theory (with the trigger code and such) you could actually talk about it- i mean any other asspects of mental health you can.

perhaps it's because this site aims to ease these feelings and make you feel better

you see it all the time- chat to reduce feelings of self harm, or bipolar support, etc etc etc.

what ever.. maybe that comes in to it
