Help me understand what I'm doing wrong in my life?

during vacation in August I found pot in my 17 year old son's luggage, the last week of August I was in the hospital with diverticulitis, the second week of September my house burned down, the last week of September my son attempted suicide, days later my youngest son needed an emergency appendectomy, last week my step father physically assaulted my mother, hours ago I was in an auto accident and my car may be totalled. I am emotionally beaten to a pulp. I already take medication for major depressive disorder. I've been praying and praying, I don't know what else to do. I've never been the type to say why me, I'm always the one saying why not me, but I can't take any more.
