What are you afraid of?

I am desperately afraid falling and the resulting impact. In the sense of emotionally and physically. I don't like being hurt. it's happened too many times before now, what should make it stop? What if I fall in love, and then I get my heart broken again? What if he end sup like my family, exactly like my family? I couldn't handle. This is one "what if" I don't have the courage to explore.
