I feel for you, Woody. Mental illness can often be a bigger strain on those around than on the patient.
Having had some experience, without being an expert, it's a criticism of doctors that they often give out pills without being overly aware of the whole picture. Not saying that's what's happened here, but it's a thought.
You don't say what the diagnosis is, and mental illness can mean many, many things. As a first step, try this lot. If that's not what you're looking for, they will probably be able to put you in the right direction.
