I've just become so numb, I've always felt as though my family don't give a **** about me I mean if anything they always used to hate me, shout at me, beat me and not give a crap. I can defend myself against any **** they say to me including "I wish you would just die" or "I will kill you" or "I will beat you senseless" or "I wish you were never born", the usual. Funny thing is I never did anything that bad as a child cos I never drank/smoke/bunked school. I've always felt singled out and absolutely hated them because even after all this happened they'd expect me to carry on like normal and talk to me like normal 5 mins later... they've never said sorry to me about the things they've done.
I was lucky to have a partner for 4 and a half years throughout the **** they put me through but the relationship was incredibly turbulent, I found that she was cheating on me, we tried to make it work and the relationship changed although we made it 'work' for a further year and a half... we got into quite a few heated arguments and they became the norm, we used to hurt each other, I used to self harm and I stopped eating but I covered my tracks well, nobody else noticed either of these things apart from the obvious weight loss. At this point in time we've just left talking to each other.
Since then I've grown up and I feel like I don't know who I am, I feel so detached and numb. My brother and sister have since screwed over my parents and hurt them a great deal, which I've never done but they're still favoured over me. My sister self harmed and showed my parents and told them she's thinking of killing herself and I'm just thinking what the hell? It's attention seeking. I have no sympathy, I know I've become this horrible person but I don't care. I just wanna know why and whether I've gone past the point of no return...
I'm close with my group of friends but they don't know any of this stuff, it's my 'dark' side which I don't indulge or share with them. I just like to have a laugh and enjoy the time I spend with them, I'm quite sarcastic too.
What do I even do? [Serious answers only please]
