I have been told, and maybe this is true, that hell is meeting the person you could have been. My understanding of hell is that it is more the limitations that our choices place on us which keep us from progressing, rather than a punishment that God places on us. I don't think that punishment is God's primary method of working with us, or that God is essentially punitive by nature. He wants us to do the best that we can, and will be disappointed if we fail to reach our potential, whether by choosing not to continue this life until He calls us home, or by choosing a path that doesn't lead us to Him. He wants us to return and to grow and progress and become like Him. But if what we choose is something different, God will not force us to make a different choice, and if we don't prepare to continue our progression beyond this life, we will limit our own options.

Most people who consider suicide are not happy with who they are and how life is, and they want something to be different. But if you die, you are still the same you that you were here, only this is a place of change and growth. I believe that change can still happen and there is still hope on the other side, but it won't be a shortcut. If anything, change will be harder there than it is here. Healing can still happen, but I don't think that it will be automatic.
