I never had a father

I'm starting to realize that my lack of having a father figure in my life is the cause of many of my problems. Not all of them but many of them. Especially my general self esteem issues. My biological father and I rarely talk. I think he cares about me to a small extent or at least he did once. But he doesn't love me. He never loved me and I think I know why. He and I have no relationship and he has always loved my sister instead. He didn't treat me well in my childhood and I'm not particularly close to my mother either. But at the very least she treated me a lot better then he did. I find myself longing for a father figure in my life.
