How to know if chakras are balanced?


How would a person know if his/her chakras are balanced or not.
If there are imbalances how to go on about correcting them, would the youtube videos be enough to follow or does it need guidance?

I tried this website and it gives me my vishuddi chakra is not balanced.

However, when reading about signs of manipura chakra, I feel that this is the chakra thats not proper. How do i know for sure?

I am still a newbie in yoga and suffer from anxiety quite a bit nowadays.
