My mom bites me

Your mother may not bite you because that is abuse and you can report her to a social worker or the police if she doesn’t stop immediately! You don’t say how old you are so it is difficult to give advice. If you are still a child, then obviously she will be upset if you come and go at will. If you are older, then you should have a heart-to-heart talk with her. Tell her how you feel and that you want her to trust you. Then, is she allows you to go out, don’t stay out longer than agreed upon and always go the place of person you said you would. I hope your mother reads this and realises that she should not revert to violence because she could end up in big trouble.
