What can I do to cure my condition caused by a makhluq inside my body?

I do work of tabligh. I can feel inside my body have makhluq like jinn. That makhluq is controlling my mind. That makhluq makes me to do bad thing. I find it difficult to sleep if sleep I have bad dream and it is difficult to wake up. Sometime that makhluq makes me afraid until I can’t drive. I think that makhluq is long time already inside my body. I go many places already to cure my decease but failed. Please give me advise or any suggestion what to do.
