Man did not create life and should not decide himself on its termination. Also, the death of the body is not the end of existence.
All religions teach that consciousness and self-awareness does not end at death. Some religions teach that Liberation is the ‘end’ of existence in worlds associated with matter, and moving on to the next stage. Consciousness and awareness of personal actions, as even Catholicism teaches, does not end with death. In many religions, the vision of God, and being in the presence of God does not ensue after an attempt on life. One has to come back and finish the round of suffering, accorinding to many of the religions of man.
If someone has a hard time then it may be helpful for him to have the awareness that everything in this world is changing and fleeting in nature, and that what seems to be terrible or tragic today, tomorrow or the day after will turn out to be bearable and in some cases good or even extremely beneficial.
One needs to take into account the factor of time, which heals all wounds, and the fact that man is never left to himself alone, even if close ones, friends and acquaintances all turn away from him. There always is God as the final refuge - someone good and loving, and at the same time always present, although invisible. You may and you should ask Him for help, for support in difficult moments for settling issues and conditions, or, when the latter is for any reason impossible, for a change of our attitude towards the situation in question.
No situation is hopeless. To tell the truth, there is no situation without a solution. Keep turning towards God and His love and you will get better right away.
Another important factor is the law of cause and effect. The present state comes about, among other things, due to the past actions of a being. It is sensible to try to get through it to the end and thereby close the issue. Otherwise, one has to face up to the same consequences again, having the added burden of this not thought-out action to discharge. Now or at any time later it is impossible to circumvent this law.
Whatever a man might do, God is always on his side. Difficult moments will pass by and the sun will shine again; joy and love will come back. But you will always find joy and love in God. Smile to God and keep telling Him that you love Him very much. You will really feel lighter right away.
