Chronic Illness

How can I trust myself to be a finisher and stick with this program when I have a chronic illness?

I can cognitively make all of these wonderful plans, but it feels like my body constantly trips me up and betrays me.

I feel unable to control my body and the flares of illness. So when my body fails me, I give up.

This experience means it is even hard for me to start and not self-sabotage from the beginning.
