Hello M.,
Have you ever heard of Reiki? It is an awesome art of moving energy around in the body. I have 2 people I would highly recommend. It is nothing more than a holistic way to settle the mind and body down and all you do is lay down while the reiki master moves around you holding their hands over you and allowing energy to move.
Sometimes we get stuck dealing with things that get out of control and we just need help getting un-stuck!!! Might be a great thing for you as well.
I am sorry, but children can be very mean and say the nastiest things ever, but you must step up to the plate and not allow her to destroy the 'dinner hour' as that is the most incredible time the family can share together.
I wrote a book on mistakes I made because I did not hold my child accountable for his bad behavior and in the end, it really ended up destroying the family. Don't let one person's attitude rule the family. Set some boundaries with her and be consistent.
Massages are another thing that is awesome to mellow the stress as well as accupunture.
Good Luck M.!
