What about Fear of water? Phobias: xenophobia definition is a bit simplistic; yes 'strangers' but also more towards the fear of foreigners. Usually, used socially and culturally than just 'strangers' but I digress.
Start now. Start where you are. Start with fear. Start with pain. Start with doubt. Start with hands shaking. Start with voice trembling, but start. Start & don't stop. Start where you are, with what you have. Just start.
