No one knows what happens when you die, things could get worse after death and in that case suicide is not a solution but rather a next step towards something even worse.
Given that it is currently impossible (as far as I know) to know what happens at death, the decision to suicide is an uninformed decision of tremendous magnitude.
If by killing yourself things get worse, what would be the next step?
Would you be in a better position to turn things around in the afterlife (assuming that there is one) or now in this life?
In summary, the reason why you should not kill yourself is because you do not know what will be the result of that action your death: your death is not a guaranteed solution to anything.
