###$ relationships.

I don't know why I made the title was that.
But in other words: I could never get a relationship, don't know why. I presume because I could never find someone that could make me feel genuinely attached to. But it's not just potential girlfriends it's just about anyone. I can't connect to my parents or sister. I more like hate my parents, two idiots that decided to have children without thinking about the future, always had money problems in the house because of how stupid they were in having children instead of working for a career, and now I'm suffering for that. In fact I can't connect to anyone, even my "friends" at school are only friends when I need them; otherwise, I wouldn't care if they died. It's really sad (actually I don't really feel anything, I'm indifferent most of the time) for me because ever since childhood I felt alone because I couldn't associate with anyone, as well as that nobody ever understood how I feel. My worthless father was violent and always wanted me to go by his dumbass ideals instead of actually supporting what I liked from childhood (working and messing around with computers.. hardware, software, doesn't matter. Anything related to computers = me) and my mother constantly shoving me into social interactions with other idiotic children instead of actually trying to understand me.. and I gave a shitload of hints that yell "WHY THE ###$ YOU'RE NOT AT GOING TO A PSYCHOLOGIST, IDIOT" during my childhood yet she always was like "NONONONONO STOP BEING NEAR THE COMPUTER GO TO SOCIAL INTERACTIONS". What the hell?
Oh look where I got. No matter; I always like to boast about my parents. Lovely people.
But it's not just my parents.. I just seem to rank people based on how useful they are to me. I don't really care about others unless it's for my own good. If they aren't useful for me, I don't care about them. Interacting with them seems like a waste of time for me. If I don't get anything out of it then it's not worth it.

Guess there's no hope for me.

You said five words that really stood out. "My worthless father was violent".

It sounds as if your childhood and past experiences have affected your outlook on life, and your ability to relate. What your father did to you, and the way he acted towards you was in no way your fault. Therapy may help you to explore your feelings about your past, and your reluctance now to get close to other people. I an so sorry that you were treated in this way, and also let down by your own father. Yes, there is a lot of hope for you. The very fact that you're posting on here tells me that. A therapist can help you to explore the bottled up painful feelings, and find hope. Your father's treatment of you affected your ability to relate, and with the right kind of therapy, there is every hope that you can begin to put the past behind you and create a future for yourself in which you can begin to allow others to get close and to learn to value and love yourself.

Therapy? Damnit.. Yeah, my good for nothing mom would accept that. But hey who knows what I am, sociopath, psychopath, I believe all options are open.
Now to convince my mom about that. Damnit. It might be useful for something I want to achieve, shady business. Or maybe.. I got an idea.

allow others to get close and to learn to value and love yourself.

I don't allow others to get close because 100% of the people I meet don't share anything with me. I don't have anything to share with anyone that doesn't have anything in common with me. Also the main problem with any girl I meet: the only think I like about her is how she looks.
Oh, and I love and value myself perhaps more than enough.

You said "But hey who knows what I am, sociopath, psychopath, I believe all options are open."

And how would you know if these labels apply, without an actual diagnosis? At least a therapist could give you some answers. I can hear your anger, and your annoyance at your parents. Therapy may get to the root of the problem, and at least you'd know for sure whether or not the labels you've given yourself actually apply.

One of them could serve me well in the near future. Or I could fake depression, that can work as well.
In any case.. my mom won't move her butt at all. I'm not sure we have the funds for therapy, and if I'd say to my mom that I want to be diagnosed she'll probably start yelling and say "you're fine, stfu". I told you she's useless.
