So tired of family not understanding me

So I'm 36 and I've had panic attacks for the last 20 years and I also had social anxiety and agoraphobia for most of my child/adulthood (finally outgrew it in my late 20's) and now my family just assumes everything is mental with me. I get hives when I take penicillin, amoxicillin, z-pac, and zofran. Well today I was talking to my mom about it and she asked me if I wasn't sure it wasn't just mental because it's me taking something new (my panic attacks caused me to have anxiety about trying new stuff like soap, medication, and even laundry soap in fear of a reaction but I haven't had that in at least 10 years) and I'm like no its not mental because I literally get hives with the medications and she was even at the hospital when I took penicillin for the first time and got bad hives with it and no I wasn't scared of taking it. I once had a bad vertigo episode and my sister was like maybe it's just a panic attack and I kept telling her that it wasn't a panic attack and that it was definitely something else ( I had never had a vertigo episode before) and she wouldn't take me to the hospital for it because she swore I was just having a panic attack so I asked her bf to please take me because it wasn't a panic attack and of course it was a bad vertigo episode and not a panic attack like she assumed.. They automatically assume everything is just my mental health issues and not actual problems and it's so frustrating! People who don't go through this stuff really don't understand.. It makes me feel bad when they just assume stuff when they don't even know how my issues work! Is anyone else's family like this? I'm so tired of it. 😩
