Hard time with family

Hello there,

I am having a hard time during this holiday season. I am with my family (2 parents and 3 sisters) for 2 weeks, 1 has already passed.
I realized that I had a strong belief that family members should all love each other and that I had generated thoughts of high expectations.
My current thought is “I can’t stand them”. I want to love them but I feel “triggered” all the time. I feel disappointed and frustrated when they act or speak their mind. I can see that I am creating self-pity mindset. How do I move on with all that?
