Why do we sometimes feel that death is far better than this life?

We sometimes feel death is better than life, because our life is full of misery and sorrow. We are suffering in our yesterday and in our tomorrow. We live with regret, shame and guilt and fear, worry, stress and anxiety, and therefore, we feel that life is meaningless. It has no purpose. We have too many problems. But we don't realize the beauty of life. We don't realize that life is a very blissful and peaceful journey, full of love, because we have not understood the true meaning of life, because we don't realize who we are and why we are here. We want to end our life, and we feel that it is better to die, it is better to get out of this miserable life — this is only because we have not understood life, we have not realized the truth of who we are, why we are here. Once we do, our life will become a celebration.
