As someone else pointed out, alot of men of different ethnicities treat this depression in a different way. I think they just have a different way of coping with loss and other difficult circumstances. I understand where you are coming from, my husband told me to just get depressed once and move on with my life. He doesn’t understand that its not just something you get over in a few days and move on for it to never bother you again.
I’m sorry for your losses. it does seem like your depression is situational rather than chemical. whatever it is,discussing it wiht a doctor will help you assess your situation better than any of us can. Good luck.
