Dante Alighieri, Inferno

There is no greater sorrow than to recall, in misery, the time that you were happy.

Abraham Lincoln

In this sad world of ours sorrow comes to all and it often comes with bitter agony. Perfect relief is not possible except with time. You cannot now believe that you will ever feel better. But this is not true. You are sure to be happy again. Knowing this, truly believing it will make you less miserable now. I have had enough experience to make this statement.
