I usually feel like I am messed up in the head...but doesn't mean I am a worthless person(even if it feels like it) so pretty sure you aren't useless or worthless. Having mental issues is nothing to be ashamed of....people shouldn't be ashamed if they have cancer or a chronic pain issue so why should it be any different with mental problems.

I don't cut, have come close but yeah just not something that happens I've more intentionally abused drugs when I want to self harm but not attempt suicide or I've hit walls or hit my head on them and such which is more painful than it is to the walls, but i have been suicidal more than once, even lately I am having a difficult time with the prospect of continuing life.
