Never debate religion and what does religion have to do with depression.
Some very famous people suffered from depression. Abraham Lincoln and Winston Churchill come to mind.
It is really good that athletes and actors and actresses have talked openly about their struggles with depression. I hope that is causing the stigma to go away.
Good luck with your husband. There are quite a few medications he could take to help him and even though almost every medication has side effects some are worse than others and many side effects go away after you take them for a time.
Long story short depression is treatable and anyone that doesn’t seek help is hurting themselves and the people they love. Life is too short.
Once again congratulations on beating cancer. You deserve to enjoy life.
