Sick

 I am sick of people treating me like I'm an idiot or a child. I should be a Grandfather by now and I've never been married.

Infantilization is when an adult is being treated like a child, even though nothing about their mental, physical, social, or intellectual wellbeing requires such treatment.

Oftentimes, parents are guilty of this to some degree as their children are growing up, particularly when they are teenagers and trying to forge their own path.

That said, infantilization can also happen in both friendships and romantic relationships, especially if someone is trying to demonstrate superiority.

I should have been a Grandfather by now and I've never been married. No Children.
