how do i know if im belting i know people say all that stuff about using chest voice and head voice but is there a way to know if your belting like with a specific feeling in your body or something

Belting is typically a full sound with a bit of "edge" and brightness to it. Each singer will feel sensations differently, but when you're in the typical "belt" range (Ab4-Eb5) and you achieve that full but bright sound, take note of what you feel!
