Just about all of the entities who have suicided, and been contacted via mediums later, have expressed profound regret at having done so.
On the other side they can see the anguish and pain they have caused loved ones, and can see the selfishness of their act.
They also find they must return in similar circumstances to atone for cutting short the life they were given, and to work through the problems they chose to incarnate with in the first place.
Suicide is a delay, like skipping classes at school. The only loser is themselves, but with the help of their guides and perhaps a long period of recuperation, they are given another chance to overcome their difficulties in the physical.
