Negativity

I realize that I can be a fairly negative person at times, and I'm usually (sadly) OK with that. But lately, I just feel icky from my negativity and that of those around me. It's like I can actually feel negative energy attacking me somehow, and I don't like it. I need some positive influences! And I'm certainly not getting that at work! I guess I could strive to BE one of those positive influences at work, huh? :) :( :) :(
