Am I condemned to loneliness?

I've lost over the years everyone who was ever meaningful or close tome. I've been living for years now alone. I miss having someone to sharethoughts and dreams and emotions with, but I've also grown used to this emotional detachment from others. Now I have the opportunity to get close with someone amazing but I fear I won't be able to make that step. Between the desire to love and the fearof loss falls a wall that keeps blocking me. Am I doomed to be alone the rest of my days?
