How do I get over being ashamed of being gay?

I realize that I let anyone (male or female) who wants me...to have me...and it stems from being ashamed of my uality and not feeling good enough for anyone. I don't even try to date or get to know people on my own cause I have such low self-esteem, and I realize it's because I'm ashamed of being ...I don't love myself...subconsciously....so I'm doing everything to hurt myself consciously and I didn't know where it was coming from..until now. I'm a confident person overall, though...this inner/subconscious hatred is..ruining my friendships/relations...etc. How do I get over being ashamed?
