Chelsea,
Anger is always there lurking behind your shoulders. But with awareness you can slowly start to recognize anger before it takes control, ie catch it when it “springs up”. There are many ways to practice awareness and I respect them all, and I won’t suggest one method over another here.
This is a long battle and there is always a “retry” option if you failed. No need to add unnecessary burden of guilt if you had to let anger reign this time, try again. Just don’t give up.

Cheers,
TT
