Dude...caring is not pity. Caring is hard work. Seriously hard work.

And stop comparing yourself to others because you do not know the troubles they have endured. You only see the outside. They do not know your troubles, either.

I'm am sorry that you are in a difficult place. I've been there many times. I can tell you that you'll feel better if you look outside instead of inside. This life is a not a race, my friend. We are all here for our own reasons.
