I think a big part of my own recovery has been giving myself permission to say NO. If I don't want to go places and do things that won't bring me joy, I say no. I was overcommitted, and miserable, because of my own people pleasing ways. It took me a while, and I did it a little at a time. However, now, I guard my peace like crazy. I do volunteer and do some things, but it's things I have chosen and want to be a part of, the difference is HUGE!
I do realize you have commitments you cannot change. However, make sure you create time and space for you, and during those times, do things that bring you joy.
Give yourself permission to say no, and when you say yes, make sure it's because you want to!
