I'm going to tell my mom to get a hobby
Are you doing this out of concern or so she can leave you alone?
Yes. She always wants to control my life.
It is very understandable not wanting you mother controlling your life. Thus you should talk to her about it and not treat her disrespectful by telling her what to do.
She's not actually succeeding in controlling my life. I can do anything I want.
It sounds like you two needs to have a good talk, set boundaries and find a way to mutually respect each other.
