<human>: I'll try to explain this in the most accurate way possible.

I'm 21, female. My father and mother divorced very shortly after I was born. I would only see him occasionally some weekends, but never knew why my parents weren't together. I also have two sisters from his previous marriage, and one older brother who is fully related to me.

When I was in high school  I found out my father was gay, and I came to terms with understanding his sexual preference for being the reason behind my parents divorcing. I was never really told further about the specifics, but I loved him anyway. 

In the last few years, my mother finally admitted to me the alcohol, drugs, and prostitution with men (unprotected, mind you) while she was pregnant with me, that my father was doing, and ultimately decided it wouldn't be fair to raise us with his selfish lifestyle. My mother worried for a very long time that she may have contracted some sort of STD, or that I would have during her pregnancy. Thankfully, we are both clean.

Recently, I found out that my father still engages in this behavior. He's been unemployed for almost 6 years, and using the inheritance from my grandparents to pay for all these favors. I think what really shook me is that many the male prostitutes are just slightly older than my brother.
I'm trying to cope with the fact that I feel I was cheated out of having a family. I know I will always have my mother and brother, but there's this empty feeling as if we'll never be completely whole. I almost wish I never found out. I feel as though my mother had to struggle so much more by raising us by herself, and that we had to be subjected to so much fighting and bitterness that it really impacted how I feel about the people who enter my life. I want to learn to let this go, and I'm not sure how to.

Can you summarize the given text in a few sentences?
<bot>: I have daddy issues. Should I try to confront him with what I know, seek counseling, give up? I'm at a complete and utter loss, and I don't know how to look him in the eye.
