Whats your biggest Fear?

My biggest fear is to stay alone on the earth.Nobody will exist or they exist but I don't see them.I won't see anything,hear any voice so that my brain will be completely void.I will incurably look for my friends and parents or wait them to find me.I would be like an air bubble in space.I will be dragged from some place to another in space.

That is probably one of the biggies for me; Another is not realizing my ambitions as well.

My biggest fear is not being everything I can be in life. I want to be able to help people, and hopefully give joy and hope to people who have little or nothing.
