Visiting my parents and being around them is a chore

I have no emotional connection to them. Is that normal? I feel so bad about it. I’m 28 and have a 2.5, married. They want a relationship with my son and me but I cannot seem to connect at all and I am never comfortable around them or can be myself or honest. Anyone go through the same thing? They are not bad people but I’ve been through a very rough childhood and teenage years were bad with them. They never connected with me emotionally so now at this time in my life I cannot connect with them and like I said seeing them is a chore/obligation. None of my friends can relate neither my husband so I had to vent somewhere and thought this might be a good place. I know I also need to seek therapy too and bring this up also.
