Lost in life...I need help and guidance..10 points to best answer. Please help me?

I'm going to make this as short as possible..bare with me..I'm in college now but going to talk a bit about my highschool experience. I had physical and mental problems going into highschool and got caught up with the wrong crowd all through highschool but finally found the courage to break free from the bad influences when I graduated and finally got rid of a lot of bad influences. The bad thing is that I didnt carry really any positive relationships after I graduated highschool because I wasted my time with the wrong people. I have been betrayed so many times it's sickening. I feel like a few crazy people might pick a fight with me if they see me out again. People whom i stayed in touch with after highschool betrayed me and stepped all over my friendship. I now barley have any people I hangout with. Im behind in college right now and haven't met anyone new there. My family is totally ****** up and plays power games with me because I'm a male. I am tough and do everything they ask with all of my problems but they still treat me like pure ****..i feel like a slave most of the time. And the worst part is they talk horrible about me...I literally feel like I have no one or no happiness in my life anymore. I haven't been with a girl in many years and the bad part is that I am good looking (been told my whole life..not like model good looking but I have good looks)..I'm mad I was such a screw up in highschool and so weak...i feel like I have nothing bc of it..I barly suceed in anything and this is too depressing..Im so confused and fed up that maybe I should just learn to cope with being alone and just stop trying to be social? I really dont like being lonely right now but it seems like my only option..Someone please help me....
