I have to agree with WingCommander:
Let your mom know that you sense or feel that she is not really happy living with your family and that you feel you are a spiritual hindrence to her.
Also, let her know that you feel she could really use her own space and privacy and would be willing to help her find a place of her own. Also state that you are certain others in the cong, since they are so loving, will assist her in any way they can.
This way you will be showing her still love and respect and also finding a resolution to your situation.
