I"m sorry to hear of your loss.
I don't think this is right, though. There are countless examples of people who tried to commit suicide through poisons, guns, and jumping from buildings that have, somehow, survived. They then have to go through their life with whatever injuries they're done to themselves - some of which are horrific.
It's true some examples may be attention seeking, but to state it, as you seem to, that all failed suicide attempts are simply attention seeking, is way off the mark. People try once, twice, three times before they succeed - the first and second time wasn't attention seeking, it was failure.
IMO
