you are, I assume, an adult now, and as such you are entitled to respect and your dignity. Your mother is bullying you, and as much as you'd like to honor your mother's request, doing so would be disrespectful to yourself.
Sometimes, you've got to teach others how to respect you. Draw the line. Let her know that you won't be going to church with her, and that you will leave the house should any of those church friends show up with the intention to "lay hands" on you.
Tolerate one another, just as I have tolerated you.- Jesus Christ?
