JV - Have you ASHKED your H if he would go see a psychiatrist, or are you ASSuming he wouldn't go? Sometimes, when they confess all this to you, it means they are actually ready to get help.
If he's not willing to go - please go out and buy two books by Julia Ross - The Mood Cure and The Diet Cure. The Mood Cure addresses nutritional approaches to depression and other disorders, using diet and supplements. The Diet Cure has a chapter which deals specifically with nutritional repair for bulimics and anorexics. (You may also want to get a book by Dr. Amen, Change Your Brain, Change Your Life ).
If H will read these with you and try some of the approaches, great. If not - would he be open to taking vitamins that you give him? Based on what he's saying, 5-HTP would be a good start - he needs to have his serotonin levels raised, and quickly. It also helps with bulimia and compulsive behaviors (that's why Prozac is used for these things, because it raises serotonin levels too).
Now - as to the gambling - you need to protect yourself financially. He's confessed he can't stop. Cut up the credit cards, move the money in the bank, do what you need to do.
Approach H kindly and with confidence - that he is sick and you WILL help him get BETTER, you will NOT give up on him.
