If you have a physician, you might get a recommendation from him/her. I'm also a long time member of AA (Alcoholics Anonymous) and since going to those meetings I've become aware of numerous local groups which people attend that I've never been aware of before - CODA (Co-dependents Anonymous), ACOA (Adult Children of Alcoholics), Overeaters Anonymous, Alanon (families and friends of alcoholics, a meditation group (recommended by a friend), the list goes on.
The reason I mention this is that one of my fellow AA's joined a bereavement group after losing her own brother quite suddenly - he had emotional issues. I'm not saying that these particular groups would necessarily apply to your situation, but you might get a recommendation of an appropriate group from a physician - or even find one in the yellow pages or by an online search. And these self help groups, in my experience, only pass a basket asking for a dollar, if the member has one.
I wish you all the luck in the world - my own mother developed dementia and said many things to me that I'd rather not remember.
