I Don't Know What to Do

I don't know how to help my husband. Over the last two years or so, he has started becoming somewhat depressed. Once so patient, his temper is getting shorter and shorter. He seems to have lost all motivation to do anything in life, slacks on house work that he's normally done with no problem, no longer works out which he used to enjoy doing, etc. He doesn't drink, or do anything like that. It's like someone flipped a switch one day a couple years ago, and it's just been a downward slope. He picks fights over stupid small things and makes them a big deal. He went through a rough patch where he had been fired from a few different jobs, all for different reasons. He has had a steady job, (A really good paying one at that.) for the last year, so that seems to have leveled out. I know he felt a huge jab to his ego during that time period of losing job after job. Anymore he seems like a shell of himself. In front of our friends and family, he acts like he's perfectly fine. He's funny and social, etc. But then once we're at home, he totally changes. Our fights have become worse and worse, and I've caught him in some lies. Nothing HUGE, but lies nonetheless. Most recently being our water bill. Stupid, right? He's terrible with money, so I handle our finances. He had only the water bill that he would pay every month by dropping in the drop box which is a block away from our house. Long story short, I find out that he missed a few payments because he forgot about it. Our normal $30/month bill snowballed into $500. He started selling personal items behind my back on Craigslist to payoff the bill, hoping I wouldn't find out. He had only been paying our normal $30 so I wouldn't notice more $ missing from our acct. I confronted him about it, and he came clean. But this had been going on for nearly a year. I haven't ever caught him cheating, or talking to other women, nothing like that. He often tells me that he feels lost, and like he just lost his way in life. He doesn't know why he's always so mad. He's tried counseling, and reading the Bible, but they don't seem to help much. FYI, being medicated is NOT an option for him. Some days he feels OK, and others you can tell he's just miserable. I don't know how to help him. I've tried everything I can think of. I bought tickets for a band he likes, took him to a baseball game because he loves the sport, etc. I don't know what else to do. I feel helpless...
