Mother swears I’m autistic when I’m not

for years my mom has said I’m autistic because I’m not the best socially (I have diagnosed social anxiety) but she will always bring up how I’m on the spectrum so I asked my other family members about it, my dad, grandma and aunt. And they all say I’m not and my mom shouldn’t be saying I am because I was never diagnosed. I don’t know what to do it gets me mad because even though I’m not the best socially I’m not autistic and I know this for sure. has anybody else been through a similar situation?
