Anyone else still treated like a kid by their family as an adult?

I’m 24 and I’ve struggled to grow up, partly bc of mental health problems partly bc I feel like my family conditioned me to be stunted. They perceive me and treat me like a child and never helped me develop, I feel patronised and infantilised and it’s frustrating- leading me to be quite resentful. Like the other day for example my mum and aunt were talking about the age of work getting older, I voiced my opinion saying I’m concerned about what that’s gonna look like for my age group in the future and they just giggle and say ‘awhh hehe don’t be silly you don’t have to be concerned about that now!!’ Like I’m 5. They also still do **** like say ‘clever girl!’ And call me little one and more patronising things. I’ve voiced my anger about it many times but nothings really changed, my mum once said I’m treated this way bc I’m the youngest and it’s endearment. I don’t really know what to do, I can’t distance myself from my family bc they’re still a need in my life and I’m still living had home struggling to leave it. I was wondering if anyone else around my age still are treated this way too?
