U/cocaine use/ self rehabilitation

Ok, I have been an avid user of coke on and off for 7 years. I've tried stopping numerous times before without an issue. This time I've realized it's really taken over my life and I stopped cold turkey. I swear I'm stuck in this endless cycle of sleep (I don't want to get out of the bed) feeling nauseous and then uncontrollable hunger. I don't know what to do or what comes next.
