OP,
What you did was so normal, but soooo brave.
You got out.
You met someone.
You created a good life for yourself.
You put all the shit you experienced to the back of your mind and focused on making a better life for yourself.
And you did it👏
But you have your parents twice a week stressing you and picking the scab that is your childhood.
Your sister's are different, have a different character to you, can't deal with what went on, so deny it.
You know IT was wrong.
You know THEY were very wrong.
By posting on here you have made a massive leap forward.
You are acknowledging and beginning to accept that you are fxxking angry, and you have every right to be.
Take your time, reflect on how you are beginning to feel.
See how it sits with you.
Take your time over it.
Do this at YOUR pace.
Looking for a good therapist to explore how you feel could be very good for you.
Leave your sisters to their reality.
Focus on yours and what you are feeling now.
The greatest thing you could do now for yourself, is to accept that you are seriously pissed off with your parents and that you have every right to be.
How you channel these new feelings and what YOU decide to do, you can figure out going forward.
But twice a week seeing them is a huge amount.
I think seeing so much of them is the reason your anxiety is so heightened.
With every good reason.
Remember you are a hugely strong person.
You left home.
You created a successful life for yourself.
You chose a good man.
You are raising happy, loved children.
You have broken the cycle of abuse in your family.
You are a huge success story in your own lifetime.
Don't allow your parents to rain on your success.
Seeing so much of them is THE downer in your life.
You will get through this.
