I've started doing the, "Find three things to be thankful for every morning" routine. Seems a little corny to me but it also has made me aware of how good I still have it despite the heartbreak.
That's what I do too. It does make me feel better.
You can call me Dory/ Grl.
As a wise fish once sang,"Just keep swimming!"
It's no use to go back to yesterday because I was a different person then.
