I think it's especially hard for men/women who are so use to burrying their emotions.. that they aren't even sure what they are thinking.
I still have times like these... and it's been 4+ years... and I had been using food to supress some of my feelings. Now that I have quit that - i'm replacing it with exercise.
It really is a personal effort to battle these beasts we lit up with drugs. Not fun.
However, the kids might think it's fun to go to the park while I walk around the track with just my thoughts keeping me company. I don't need music... as i'm pretty good at talking to myself.... and it helps think things out. Weird.. I know!
