I am so sorry Rose. My mother and I have had a strained relationship my whole life, so I can understand your being deeply bothered. When I have, what I term, Mamma Drama, I feel the feeling and let it come, then when I am done with it, I put a bubble around it, let it float up into the sky until I can't see it anymore, then do something I enjoy to replace the feeling of angst with one of delight.

I hope something like this helps as it's all I have to offer.
