Does anyone else get ridiculously happy over comments?

I published my first fanfic on AO3 recently and I'm very happy about it. Everyone's very nice.

One person has commented and read every chapter and leaves their thoughts everytime. And it makes me so happy!

I love it when they or anyone comments something nice or just in general. I didn't even think about it before. But seeing them is just amazing.

Seriously, I'll post a chapter and wait till I get comments, read them. And I smile like an idiot for like an hour.

It could just be something like "Good chapter" And I'd get ridiculously happy.

Does this happen to anyone else or is it not normal? :)
