Yep, I do. It comes and goes, but as more time goes by, it happens less frequently. Rejection is a big part of it all - and I think its normal, even when its not rational or logical, to feel rejection after a break up. Even when we were the ones who wanted it to happen!
Emotions don't always make sense. The better I get at accepting that, the more peaceful life is.
It's a process - one step at a time, one day at a time.
