The knowledge - the understanding helps.
I had a therapist who really helped me examine my experiences and understand why certain things triggered certain behaviors.
He once described my reaction as someone hitting play on a tape player and me not being able to pause the tape or stop it.
Understanding the programming my early experiences created has helped me understand how to reprogram - and it helps me recognize when the tape is playing again so I can pause and ask for help to stop.
Glad you are finding a path.
