On bitterness and love or occupational hazards of having emotions

As I was walking my dog something occured to me. It is interesting how when you love someone, and offer your heart to them, but they refuse or don't even notice, you don't become bitter. You may have bitterness inside you, but you never show it to your beloved, because she is your beloved. The bitter feelings, anger, sadness, bitterness and confusion, grow inside you, but you would not harm the person you love with them. Instead they come spinning out at the people you know, and at the world. You blame the world for your troubles, and blast it with your hate. Then the hate is spent, the world is angry at you, and it all starts over again. Gotta find a way to break the cycle, otherwise you'll end up on the bad side of depression. Hm. Yup. Depression stinks. All those emotions, spinning around, crashing into each other and causing nasty messups... Wow... Kinda shocking, but it doesn't really matter. After all, this is just a philosophical babble that may not have any real-world purpose.
