I don't have the answer WHY it all happened. Just know that you arn't alone when it comes to more then one loss at a time.
When i was 16 i lost my Dad, my Grandpa, and my dog all in 2 weeks.
Then when i was 36 i lost my father in law, my brother and my dog in 18 days.
It always seems not to just rain, but POUR.
My sisncere condolences go out to you, my friend!!!
