I found that I was crying a lot this spring. The least thing would cause me to cry. My daughter said the same thing. I take a high potency probiotic daily and realized I had stopped taking them. I went out and got another bottle. A different make. ( they used different straine and I wanted to cover them all ) I take one in the morning and one at night. The tears have stopped. Alcohol kills off the good bacteria and causes depression. Change your diet, get rid of the junk food (If it comes in a package or box, don't eat it.) Get into an exercise regimen. Anything from Tai Chi, Yoga, Join a gym, Swimming, anything to move. Buy a lawn mower and mow lawns for a second job. You'll meet and talk with people. Doing things for others really helps lift depression. Meanwhile, you and your wife are in my prayers. God Bless You. These are difficult times.
