I'm starting to think that I'm aromantic
Why do you feel that way?
Oh, that kind of stuff is just not my scene.
It's okay to be yourself if you're not harming others. But you should seek out help to confirm your feelings before you give up on romance altogether.  It will at least help you to feel less unsure.
Yeah, I don't like or have feelings for any humans.
There are people who live their lives without any feelings of romance or attraction, and talking to a professional will help you to uncover if you really feel this way.  Since you say that you have no interest in humans, maybe you could try getting a pet, and that could be a great source of joy for you.
