How To Withdraw Remeron?

I ve been on 15mg Remeron for over a month. I m a wreck: shooting sharp pains in my hips, feel like i m out of my body, anxious about everything, indecisive, repetitive, worried, feel like something is wrong with my body, attacked, etc. Do I dare get off of Remeron without speaking with my psychiatrist? If I decide to go it alone, how should I get off of it? Oh, and I m an insomniac as well.
