I can't control my laugh?

it's not class but a study institute but whenever i sit next to my friend we always laugh and i just keep laughing even if she stops i continue laughing and i can't control bc i like laughing , i went through a lot of depression and i honestly miss being happy so i don't know how to control it and other just look at me weirdly or annoyed bc i can't stop laughing πŸ’€ they think im crazy maybe I don't know

does anyone have this kind of problem , like i really can't control myself πŸ’€
