Would BSL be useful?

I'm an a level student who's looking to do medicine in the future and I just want to know if British Sign Language would be a useful language to learn in the medical field. I'm pretty useless at learning languages that aren't English but I've started learning BSL and I'd say it's going quite well yk. Dk if its relevant but I want to be a psychiatrist and idk if it'd be useful in that field. 🤷🏾‍♀️
