I would like to add one thing :-
Indeed seek help for YOURSELF and don't really bother about the N'person....
one of the most important part is HEALING your inner self from all the injuries caused by the brutal emotional attacks.
What helped ME was 1. Meditation (essentially deep breathing) 2. Reading up on the internet and seeing that I am not the only one (strange solution but somehow blunts the edges) 3. AVOID medication for yourself. ( Although ayurvedic medication helped me TOTALLY from severe pains in the chest ... but a tendency to depend on medication started erupting within me... i guess you could call it "addiction")
Basically well wishers who will be empathetic to your condition ... works wonders ...
Cheers and Best wishes.
