Men and women respond differently to mental suffering, but both can benefit from different things. In summary, women, for the most part, jsut want someone to feel bad with them for a while. They're not looking to be fixed, whereas men tend to be more analytical and goal oriented in problem-solving. Guys want stuff to work right, so they try to fix stuff. Men and women both seek both of these forms of comfort, but one usually overrides the other. You seem confused as to exactly what you were seeking. It seems the emotional part of you wanted some empathy and care but the analytical part of you was left unfulfilled concerning the need for the pain you went through.
To find an answer to your question about the need for suffering we have to start way back at the garden of Eden. Adam and Eve were perfectly happy living in a world where everything went right. Here's a question - do you think they appreciated it?
A scripture answers this for me. "It must needs be that there is an opposition in all things. If not so, righteousness could not be brought to pass, neither wickedness, neither holiness nor misery, neither good nor bad.Wherefore all things must be a compound in one." Suffering happens for three reasons that I can name off of the top of my head. First, and most evident from the scriptures (but not the reason for your suffering) is sin. Sin brings pain.
Second, suffering hellps us to appreciate the good things more, adding joy to our life. We can only experience joy to the contrasting degree to which we have experienced sorrow.
Third, suffering helps us to grow. You learned things from your experience. What you saw and felt will make you a better father and help you to understand others' suffering. It will help you to empathize with others going through similar circumstances.
Why does God let us go through all this, then? It's all part of the plan. He gave us free will so we could learn the difference between right and wrong ourselves. Some people choose wrong will their free will. They sometimes suffer and then realize that choosing right is better. Some of us see others choosing wrong and it helps us to utilize wisely our free agency in choosing right.
Another scripture should wrap up the Gospel application of suffering: "thou knowest the greatness of God; and He shall consecrate thine afflictions for thy gain."
Christ had to suffer all so He could understand us and take that suffering from us. If we let Him He fix us, but He is also there to feel bad with us.
