It's nice to know that I'm not the only one. Thanks.
It's another thing I have to work on. It's ironic, because it seems harder to fight it...but then you feel cr*ppy after. I'm always mad at myself or feel guilty for putting myself through something that I could have avoided with concentration.
The other thing is I have an obsessive personality, so when I "want" something, eventhough I know darn well that it will upset me, I can't let it go. I cannot just focus on something else.
