There can be nothing more devastating than losing a child or any loved one. I don't have words to tell you. I understand severe depression as my wife has had it since before we were married nearly 56 years ago. When around others she is very charismatic and lightens the room. However, she rarely wants to see anyone so she shuts everyone out. It is so very difficult to watch. I can almost feel your sorrow. God bless you, your wife and the rest of your family.
