Anyone else labeled "mature" as a child but are now labeled "immature" as an adult?

Delete if this isn't okay to post here, but I'm too afraid to post in r/ADHD because of the things I've heard.

As a child, I was labeled "mature" and was told I had an "old soul."

Now, as an adult, I'm consistently called childish and immature and it really hurts. I don't know why I can't 'act my age' sometimes but I wish I knew what happened.

Anyone else have insight for this?
