Depression is very often a chemically based condition. Depression can stem from may things and no situation or circumstance gives someone a "right" to be more depressed than another person. You feel what you feel and it's real. Sometimes, and I believe this can be more challenging for men, you need to get your BRAIN in chemical balance (which may require you to visit your physician or even possibly a psychiatrist). You may need to try to find a medicine to help you deal with this season of depression. Then, once you find a medicine that works for your brain, you may be able to identify more clearly some of the "triggers" and challenges that are causing your underlying depression and make a plan, along with your wife, to try to work through these challenges. Good luck!
