Sharing medical history with parents

I’d like some honest opinions about my situation and I want to know if I’m right or if I’m crazy for thinking this way because I’m definitely being made to feel that way by my family and maybe they are correct.

I am 21(almost 22),in college trying to transfer, and I moved back home with my family due to a previous college transfer. I have a growing list of medical conditions and issues that over the years I was told to ignore by previous doctors until I turned 20, switched doctors and ended up getting taken seriously (by both my parents and new doctors) and a lot of serious diagnosis were found through frequent medical appointments this past year. I get lots of blood panels etc taken because of all the random things my body does. I absolutely adore my new medical team and they really listen to me and get results.

I am not close with my family. They think we are close (like I’m sure all parents do) but to be honest they are the greatest cause of stress in my life and moving out is the light at the end of the tunnel for me. So, I was recently diagnosed with Mono (what I was diagnosed with doesn’t really matter to me, it’s the principle) after a complicated diagnosis process my Dr did the mono blood test as she originally wanted to do and got a positive result. During this time my family talked with other relatives about my sickness and what I should be doing and what I should be taking etc etc. This happens every time I’m sick, and with relatives that I’m not close with (I’m not close to any of them) and even just family friends. To me this is a huge invasion of privacy. They don’t see it this way. But now I have relatives (who were veterinarians so yes technically medical school but still) messaging me about my symptoms and asking about lab results about something I didn’t share with them in the first place. I have no issue asking for help or for outside opinions but I think that should be my choice to make. I even have a dr appointment to go over all results tomorrow wich my Dr went out of her way to provide for me. My family says I’m being ridiculous and have an obsession with privacy. They say I’m in a family so it shouldn’t bother me and family members and outside opinions should be welcomed. I somewhat agree but I need to consent to it first. Idk- someone tell me I’m crazy lol
