How can a person feel love?

I've experienced a lot of sadness, frustration, abuse, an anger from my childhood days to being a teenager because of my parent's methods of parenting, which is the authoritarian parenting style. I'm single right now and living with my parents, but when I start to live on my own and start dating, I don't think I'll experience the feeling of love. All feel is anger and sadness. How can I feel the love of my lover with what I went through as a child?
