My room mate has hypnotized me and has messed with my head. What do I do?

I've roomed with this guy for about 10 months. He knows hypnosis and has hypnotized me several times. It wasn't until recently that I've realized he's messed with my head. He can point at me and say the command "pain," and it feels as though I'm hit with a bolt of lightning. He can point at me and say the command "***," and I have the most intense ic feeling I've ever had. He's done something wierd to me. He's planted some crazy desire for his feet. He'll sit down take of his shoes, and tell me "lick, slave." I'll lick his sweaty, nasty feet and enjoy it. I'm scared of this control he has over me. What do I do? I can't seem to shake it. He uses this control over me to make me do work, clean his car. If I don't do what he says he does the pain thing. If I do what he says he rewards me with his feet and feeling. What do I do?
