I feel like a middle aged emo kid
Do you mean look like one?
I am feeling that way.
Well, if you're cool with feeling like that then it's perfectly fine.  It's your right to identify yourself however you want to.
What if I wanna look REALLY emo?
That's totally fine!  As long as it doesn't hurt your ability to work a job or leaves you shunned by people you care about, I think it's totally fine to identify yourself in whatever way you see fit!
