is it just anxiety?

Hi there, I'm 24, I've been hiding from people. It's messing with my life now since I am supposed to be a responsible man now. I quit going outside, playing and any activities in school/college. I just wanted to be left alone. The other day on the road, I noticed something. Every single movement of my body makes a sound in my head. I can hear my eye blinking, hand moving, every steps I take. It sounds like buzzz. It doesn't happen at home, outside.. In front of people. Is it anxiety?
