The strongest man can not remain strong all the time, meaning there are times life punches him really hard and he cannot bear it but he still smiles to his family, to the world , cause he is taught to believe from childhood never to show weakness, as a man never to cry.
It is not just that men are taught to believe that crying when they are down is not a good thing, it is actually that no one is ready to listen to their pains and they have learnt to take it all in and face there fears without expecting someone to come through for them. literally all the men you can think of are going through one stuff or the other but then, it has always been a situation of all man to himself and a general understanding that no man is coming to save you so you just have to man up and keep being your greatest motivation.
Committing suicide doesn't solve any problem, it even shows a sign of weakness because you are destroying your love ones while destroying your self. if you are too drained, just find someone and talk to them to ease things up because more problem is still on the way of every man.
