How about psychiatric control? Some mentor-group?
I don't see what you expect from US here. You need to be 'cause of your condition verbal is not physical restrain.
The only thing that comes to my mind is, to remove them from your friend-list, address-book etc. That'll make harder for you to contact them from your mania. If that does still not help, than you'll definitely need professional help,and maybe even medication.
Otherwise best wishes
