I get this a bit, not with everyone who has wronged me, but a few people. With me it's like I want to hurt them back, almost like what I am feeling is so horrible I want them to feel it too. Except they can't. It's mine alone.

It feels to me sometimes like intrusive thoughts which I understand can be part of depression. I notice when I am well these 'wrongs' don't matter to me nearly enough.

Depression truly is awful. I agree with others, taking care of yourself is the answer, and in time maybe these feelings will ease.
