About myself and my fear of rejection

I promised myself I was going to do the only thing I'm good at: writing.
But I'm afraid.
I'm afraid of rejection because I don't trust my use of the English language. And is mostly stupid, as I think I could write a good story, I could write a good novel...a book.
But I'm afraid, publishers and agents won't accept the books of some weird foreigner writer.And maybe is because I have depression, or maybe is my anxiety. Maybe all of these mental illness that were passed to me by some hereditary  plague, made me into a a coward. But I'm afraid of rejection. I'm afraid of failure...
I want people to read my stories, and enjoy it. Like I did so many times with others... But I'm afraid I'm the only one who thinks androgynous vampires and trapped little girls are fun to read about. Maybe I'm just overreacting , maybe everything will turn out fine. I just need to free myself from these worries, and then I'll be able to be happy doing things that I like. But I'm always afraid.
And if Ii keep going around and around and I realize I've been only walking in circles? And if no one wants to read it? If no ones wants to buy it? If no one would enjoy it?
What would I do? If that doesn't make me happy as I thought it would,what can I do?
And I feel stupid, and weak.
But it's all myself and my fear of rejection.
