I feel like it is something private and I don’t have too much time alone to do it. What can be done about it?

If it's private walk away from some people and do it if they see you be should tell a teacher or tell your parents or tell whoever's around you what happened Tell them the exact same thing and they will probably get in trouble one
maybe not

IF you feel like it's private then go to a room if you notice someone say that u want some alone time if they refuse then tell them why THEY need to respect your privacy
