Struggling with Friends and Family Not Believing Me

My dad believes I'll get better once the summer comes and I get more sun 🙃

Not so much not believing but not understanding how bad it is, or they forget I'm ill because I pretend I'm fine (I'm working on not doing that but it's a process) and I think a lot of people just don't understand how a person can be permanently in pain and exhausted but still functioning because they gave no choice

yess it's a nightmare. the weird thing in my case is that my mom is severely chronically ill and always has been. but for some reason she refused to believe that i might be ill too?? even though a lot of her conditions are hereditary? it's so weird. people just won't believe what they don't wanna believe i guess, so frustrating 😞
