Option 1: Become bitter. Not a little bitter. Soul-turning, dream-resigning, disbelieving bitter. This can be, depending on the person, the much easier option. It's certainly more straightforward. It's like a switch, you turn off. But for the person whose nature it is to care, this will undoubtedly lead to (you guessed it) more suffering. It seems so easy doesn't it? You hurt?? Stop caring and you'll be fine. Well isn't that the greatest advice you've ever heard. Care, by all means. But don't care to become bitter. Care to become better.
Option 2: Be creative. Turn it into a creative force. I know that sounds borderline ignorant to the suffering in the first place, but, the truth is that this is the moment you have no shame. This is the moment you have time. This is the moment you have you (whether you like you or not). So do something with you.
At the end of the day, the people who suffered Hurricane Sandy or a broken heart or a painful mourning (quite sure we each have gone through--or are going through--at least 2/3 of these) who can do something, will do something. I'm pretty sure bitter people don't help re-plant trees in their town.
