Tired of Negativity; My Own and That of Others

My vent is that I'm sad that I still get sucked into the hole of negativity. I'm upset with myself that I still get pulled down and lose my strength by focusing on my problems, and with what's wrong with other people and the world. My critical mind gets clogged with darkness, when it could be used in a much more intelligent way, to see things clearly. Despite my intentions and my practice of meditation for years, I still lose touch with my deepest most aspirations, which is to help and be of benefit to myself and other people, to make a genuine contribution to the betterment of the situation. I don't want to add to the negativity in the world because people everywhere are in so much pain and my criticisms don't add anything helpful at all when they are filled with negativity, in fact they just make it worse. It bothers me that i still do this (although I do it less and less year by year, month by month, as I slowly but surely grow up) and it bother's me to see others caught in this trap, and I think how hard it must be for people to get themselves out of the darkness when they don't even know they are trapped there. There is so much powerful energy in all this negativity, but that energy gets sucked down into something hurtful, when it could actually do some good, it could actually add clarity and uplift things. Negativity only breeds more negativity. But I know when people are stuck in negativity it's not where we really want to be. I don't want to be there, but it's such an old habit and I keep going back to it, and I know for a fact that deep inside nobody else wants to be there either. Even when they think they do, they are mistaken. They are out of touch with how they really feel. Because how we all really feel deeper inside, underneath the negativity, is a desire to help; criticisms have an underlying hope they will help the situation. And when we see more clearly we see that they can help once they are free of the hatred and the self justified feelings, which in the end only isolate us in our own pain.
