How do I not be socially awkward?

I am socially awkward now, my social skills are bad, I can`t even have a one way conversation, how do I fix this, my conversation skills are bad, I start a conversation by saying to someone hi and they ignore me and then when I do get into a conversation at school by saying where u from people run for me, my dad told me maybe people run from you because you are an ugly sk@nk, guess he is right. My dad hates me and tells me, ``Give up, you`re going no where in life.`` I think I am awkward. Really awkward.
