If you feel so bad for others maybe you could try helping people who need it most. We need caring people in the world (as you have witnessed). Don't let your life be a waste when you have so much goodness in you. You should try some volunteer work. There are many good agencies out there who need a caring hand. You would be surprised how good it makes you feel when you see someones face light up because you made their day. Also, why don't you smile at the kid you feel bad for or open the door for a little old lady. It may make a difference to you both. Good luck.
