Hi Kelly,
It helps me to have one main focus. Something you can physically or mentally do that you can cross off your to-do list every day. i.e. Write a page a day for your novel or work on a training program in anticipation of a marathon. If you are passionate about it, even better!
Do that.
Of course, The Past will bubble up in your mind. Regard it, but don’t give it any reality for today. Say, “Today is all about (fill in the blank). The Past will still be there to think about tomorrow. But it’s always an optional choice.”
If you must deal with The Past, hire a good therapist. Then you’re “done” with that for the day, after your session.
Best,
Inky
