I don't get it.

I've been doing boxing for a while now and everyone in my boxing gym is confident but I am still a very shy person.

Any other ways I can get my confidence up?

Have you made friends with them?

Yes, I am not shy at the gym but when I am at sixth form I get shy, it's like at certain places I am shy and certain places I am not shy.

Maybe, it's the people you are with. Turning from shy to confident takes time. And it means you have to push yourself to be confident. Imagine, you are at a place where you don't feel shy (like the gym) and you'll instantly feel more relaxed.

Yeah it's some people I don't like in Sixth form that make me feel shy
