I highly doubt that your mom is psycho. If she has the routine of making dinner ready by 5 every day, she pretty much has it together. She might enjoy being in the same space with you while cooking because she likes you and cares about you. If you are a teen who works, then you probably are just going through adolescent rebellion. If you are a young adult and not a teen anymore, I would see a psychiatrist and talk to him or her about what you wrote in OP.
