Got to ask...

ok...here is my story....Death of sister just before xmas. 4 months later, dad and my good friend died in air crash and I witnessed this. 3 months later, a very dear friend who had taken the place of sister who died, was killed in a hunting accident. I was 17 when this happened....Wouldn't you call this PTSD and what problems could this cause me 30 yrs. later.....

I would say witnessing a plane crash would be traumatic, and so might some of the other losses. They would almost certainly result in a serious grief reaction.

However, PTSD is a set of symptoms comprising a (sometimes delayed) reaction to trauma -- while PTSD could be a result of the events described, it won't necessarily be.
