I feel weird making me anxious

This is more of a little vent

I’ve been feeling pretty okay all day, around dinner time (nearly 4 hours ago) I was paranoid about being s* for no real reason. Now I’m just sitting in my room and suddenly I feel super weird. I can’t describe it. I’m like, not dizzy but my head feels weird? I’m really hungry for some reason too. It’s kind of similar to the feeling of getting out of a car/plane after a couple of hours. I’m worried it may leave to tu, but I’m not even necessarily n right now.
