Why do I get over excited over little things

Slap yourself

Why not?
It shows you are not someone who thinks they are entitled and possibly has a childlike wondemeant, nothing wrong with that.
I see you said something about anxiety, we sometimes overthinking how people view us.

Getting excited is natural so don't try to get rid of it.

It should calm with time. Unless it is being detrimental to your life. Then I might talk to a doc.

But getting excited over the little things is one of the great pleasures of life!

It’s ok to be excited at possibilities

No that's good !

No reason to get rid of it

How do you know you're over excited?

I'm going to need an example 🤨

Don’t. It’s rare and precious to find excitement in the little things. Hold on to that gift.

Because you have never seen a big thing that attracts your attention.
