My husband had quad heart bypass surgery last August. He has never been quite the same person since, he is forgetful, and now is complaining of being depressed, eg vulnerable, not wanting to leave the house. It is not all the time but he is very miserable, needless to say he is on a cocktail of drugs. Do you think they contribute or not. He now has an incisional hernia, and has to have that repaired, and it is all getting to him. What can i do to help?
