2many,
Please know that this can be worked through. It's not easy by any means. But there is hope. How about getting out a piece of paper and writing all those coping skills you learned down, then it will be easier to see which one s might be useful today. This too shall pass doesn't sound very convincing during the craving but I am finding it to be true.
Hey, get that list made and share with me(if you want) which one you think might help you today? I'm cheering you on, just take it minute by minute if you have, just don't pick up.
Many hugs and hope too,
Tammie
