I agree with Alexandria.

What you are thinking and feeling sound perfectly normal to me. You are dealing with an insane amount of stuff. It sounds like you have been for quite some time and of course this last diagnosis just makes it seem like you can't win. The "one thing after another" sort of feeling.

I would say that this would be an issue to take up with your doc, also if he isn't, get him into counseling. You guys could probably do joint counseling/couples counseling so that you can take care of a number of issues all at the same time. That is to say, the same person that is helping with your marriage would also be helping with his depression, alcohol abuse and so on. This way they can formulate a treatment plan that encompass all of the issues, addresses everything and doesn't have multiple docs working in multiple directions. That way no one is stepping on each others toes, or have you guys running in 20 different directions.

I hope things work out for you.
