What would you do

Hey everyone, I’m just seeking advice or what you would do in this situation. I’m trying to figure out what I should do when it comes to my dad’s side grandparents. Every time I see them they give me panic attacks, they always tell me what I’m doing wrong and honestly I can’t even tell you the last time they said one good thing about me. Just one good thing. I cut my limitations around them a lot to where they’ve started to call me a seasonal granddaughter because I only see them around holidays or every so often. Today I went over with my 6 month old son to go swimming for a bit, because I’m supposed to dog sit next week for them so they were giving me a key for the house. And it was so draining, it’s always something about my future/ my son’s future, or my physical features they are targeting me for. It could be anything from my weight/being too skinny, to my teeth, to my heart problems and being “lazy”. I’m just tired of it all. I left their house borderline bawling because of how awful they’ve always made me feel. (BTW THEYVE BEEN DOING THIS SINCE I WAS A KID). They just make me feel like a huge disappointment and I’ve tried telling them but they don’t listen and it’s okay because “they are Christians and it’s not that big of a deal to point out flaws” I’m debating if I want to cut off contact fully or not but again that’s my grandparents so I have mixed emotions about it, and I’m already limited on how often I go over there because it’s something every single time.
