Are you a loner by choice, or have you suffered rejections that have backed you off? And if the latter is the case, is this why you are hurting, because you know yourself to be worthy, and it makes you angry when others contradict, who can you take it out on, when they all run away...........Yourself? Oh no honey, no more cutting.
It may help you to talk about the things that are hurting, I am here to listen, but a qualified, experienced counsellor would be more help to you.
I stand here, depressed myself, and have to deal with this. But I care about others along the way.
Care enough, to keep reminding you, you are worthy, and lovable.............Of course you are.
