If I'm doing the right thing, why does it feel wrong? If I'm doing the healthy thing, why does it hurt? If I'm trying to heal, why do I feel more broken? If I'm trying to protect someone from me, then why did I hurt them?
My advice? GAL, GAL, GAL.
When you least feel like it is the time when it is the most important. You need some time to really date yourself and focus on your wellbeing.
For me, what worked best was setting some goals and looking in on them weekly to see how I was doing. Goals for parenting, for treating my ex, for GAL, for 'cleaning up my side of the street', etc, etc. Setting a plan for a couple weeks at a time and trying to stick to it.
