Will I ever truly be happy?

It seems most of my life has been nothing except disappointments. I have only two close friends. I had more in the passed. But I always managed to ruin those friendships one way or another. One out of state and the other is here. When people first meet me they like me but never want to hang out with me over a long period of time. I try so hard to be cool to be around. The passed few months I have been trying to be more sociable approachable and fun to be around. Within a short period of time I manage to irritate people. I am 25 single and have a baby girl. I would love to be happy for once in my life. Have people like me for me and want to be around me. Right now the only one who truly loves me unconditionally is my daughter. The greatest gift God blessed me with. I have recently estranged myself from my entire family. That I am very happy about. They were a huge part of my problems. So I'm happy they're out of our lives. Well....hopefully one day I will.
