Hang in there! I'm a recovering alcoholic so don't know the pain of pills precisely but I bet there are quite a few similarities.
For me, getting past that first few weeks was really important and really difficult. I had to keep surrendering and keep surrendering -- all the pain and the hurt and the shame and the pride and ego -- I just kept surrendering all that to my higher power.
And hours and days slowly went by and then I looked up and I'd made it through 2 weeks. And the way I knew, was that I had enough strength and curiosity to actually raise my eyes and head from my hunkered down position. The way I knew was that instead of looking inward and focusing on the pain, I found myself looking up and out. The way I knew that I was going to be okay was that I *was* okay.
Hang in there. Breath. Let time pass.
