How should I handle jealousy?

I am a jealous-natured person. I love women and I can't stand it if others hang around with the women I like. For example, I feel jealous if I find my best friend talking to my close friends because it creates an emotion on me when I think that the closest friend with whom my best friend is talking to might like him more than me in near future. It just creates a fear and anger on me and I feel extremely jealous. Another example is that when I see a hot blonde women is out with a black guy (not out of racim, just jealousy), it creates an unstoppable jealousy on me which is uncontrollable. I really want to overcome my jealousy and become everyone's true friend. I need a girlfriend but I can't get them because I don't have any communication skill to go over, talk and stand in front of a girl to ask her out and that's probably the master reason why I can't stand to see any men hanging around with a hot women. Please give me advice. I want to overcome my jealosy!!!
