You may find this incredibly naive, stupid, offensive but it's not. You can free yourself from the influence of these people by mentally sending love into that situation and to them. Rephrase-maybe not totally free yourself but go a long way in the direction of relief. You send love mentally by just saying it to yourself. You're not praying to God or Jesus or whomever. You just take a moment and say something like "I send love into this situation and the people involved" Name them. Do this maybe three times a day for some days. You Will see results. Stay away from them even if for the rest of your life if it works out that way. Go your own way. The love you send will work on them and on your own mind. It's only common sense that if you entertain hate and stress that is negative energy you put into your personality and you reap the results.
