Resenting the happy, will only give you unhappiness

As i sit here in front of my laptop, i start to think of how ive lived my life. For so many years ive hated (or greatly disliked) the people that cause me pain or had made me unhappy. But tonight i realize that's a selfish way to live. For some of those people its because of how they treated me, or treated someone else i care for. For some its the things they did to deliberately or not deliberately to hurt me. But now, now i see that they are happy. They have the things in their lives that make them smile, make them laugh, make them think. So i guess what im trying to say is, im happy for you, all of you. I just hope that i have affected your life, in some way or another, but know that i will always be happy for you. And if that's the only joy i get in my life, well so be it, its worth it all if i can make someone happy with my actions, or whatever i did.
