Not SIng for a while - good job!

Sometimes I don't understand why I stopped either. One day the urge wasn't really there. I have bad days when the urge is there... but I hold off.
Perhaps this is a positive step any way you look at it? Do you know how you feel about cutting, how you feel about not having done it for some time? Maybe that way will get you to an answer.
Even if it doesn't, at least you're taking good care of yourself.
