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.
You can hold yourself back from the sufferings of the world, that is something you are free to do and it accords with your nature, but perhaps this very holding back is the one suffering you could avoid.
