You got this!! For me that first week was really difficult just because my body was getting the heroin/oxy/everything else I was doing out of my body. Just believe in yourself no matter how bad you want that fix, it's not going to make things better..maybe temporarily but the agony that comes afterwords will be even worse then before. I dragged myself to an NA meeting during my withdrawals and was filled with so much hope seeing people that had years of recovery from this disease. I'm now on my 100th day clean! You can do it just take it one day at a time so you don't get overwhelmed and try to start establishing a support group. That was a great idea to tell your dealer to cut you off, that itself shows strength and the desire to live a new life.. Once I knew this was the life I wanted I deleted all those dealers and people I used with out of my phone book! "Just for today you never have to use again"
