WTF? Please! Move away!

So I actually have the, what this term was originally meant to be for (which I'm damn angry about since it makes it harder to dig up the proper phobia!), fear of open places - literally. Do you know any home treatment methods? I CAN'T consult a doctor, just don't ask, I have my reasons. It damn makes me angry that I can't walk around the town or nature without having this spontaneous shit-anxiety coming up. I have to say the human brain is just stupid, it has too many disturbing functions like obsession, stupidity, phobias etc.
