I hope that you are able to come off it safely soon. By IP did you mean in-patient? I came off venlafaxine in hospital which was pretty hard, I had extreme anxiety but it only lasted a few days - but I don't know if it wasn't too long because I started another AD, and also I hadn't been on venlafaxine very long. I certainly couldn't have functioned anything approaching like normal while going through withdrawal, so maybe an inpatient stay would be a good idea? Take care and hope it works out for you soon.
