I'm 25 and went to once here in NH and had success and havent used anything in 2 years. Its of course hard at first but it was soo good for me to be in a place for the first 30 days where I was secluded and far away from my environment. The first 30 days are a strugle and its good to be in a safe place at that time. Im now going to school for addiction counseling so my horrible drug addiction led me to the path I needed to be on. You have a purpose too , you just need to get clean long enough to find out what it is. I found it helped tremendously to not return to where I was living previous to rehab, It makes it a whole lot easier when that access that your used to isnt at your finger tips. I dont know if you have that option but it really was successful for me..and meetings of course. Hang in there and have faith you can do it. If I did it , you can do it.
