Is it normal to hate this much?

I’m a pretty negative person but I’m not saying I’m filled with so much hate and insanity that I want to kill. I always look on the downside and I end up hating alot. My friends refer to me as “Negative Nancy”. I’m pass the idea that I’m depressed. It’s strange that I’m always so negative. But not to mislead you, I live a pretty good life. I’m tired of mood swings of hard negativity, hating and being happy.
