Sometimes moving away is the only answer
I lived 21 years in my parents house & 33 in my marriage.....leaving at times is the only way to find our sanity after living with totally dysfunctional people. Just allow yourself a couple if years adjustment time. For me I actually had to pull out from inside who I really was that had been buried much of my life & let the real me who I sensed was in there finally come out. The person who wasn't constantly REACTING to the dysfunction around me but actually just living my life fir the first time in all those years. It took me time to sort it out & after 11 years there are still times where I catch myself thinking some old thoughts & still adjusting to my new life.
