hate myself

I literally hate myself. I want so badly to get married and have babies. That is my main goal in life. What is wrong with me? I just turned 20 and my boyfriend said maybe in 2-3 years. I legitly feel that is too long and it really isn't long at all. Why am I this way? Why are marriage and babies so important to me.. why can't I be normal and just want to party and live life like everyone else.. I feel so lost..
