I don't self harm, but I do have major problems with suicidal ideation.

For me, I think it's because my mood was depressed, for so long, that SI became almost a habit. It became a comfort for me. How sick right?

I don't know from a medical standpoint If this is possible. The doctors may just conclude you are still depressed if you have these thoughts. I've never discussed it much with my doctor in length. I did ask my doctor if the suicidal ideation would ever leave, and he said maybe, or maybe not.
