Family acting like im not sick

Does anyone else get annoyed af when/if your family just completely denies that you're sick because I'll be talking with my family and I'll say something like i cant get up that early because im sick and they were like your not sick which literally just annoys me so much because 1. my parents have been at the doctors appointments with me and 2. they'll literally be like oh why aren't you close with us and also like why won't you talk to us about feeling sick and then when i do talk about being sick they'll turn around and act like I'm perfectly healthy and it jus like really annoys me. also for context I have undiagnosed ehlers danlos syndrome and undiagnosed pots but I also have a diagnosed heart defect. also sidenote something else that really bugs me is when they wanna like do something and I'll be like I cant cus I feel too sick and they'll just act like i can just choose not to be sick.
