Yeah Rob, it can be devastating. I've dealt with the suicides of four very worthwile people in my life. When I reflect back and banish those "what could I have done" thoughts from my mind, I'm left with a similarity they all shared. They were very sensitive people who cared about others greatly and hence were susceptible to being hurt badly at times. They often took reckless chances in choosing partners..throwing caution to the wind in the belief that they could "change" others' behaviours. When they found themselves alone, they had few resources left to help themselves. I miss each one greatly.
