Changing your mindset, more so how you respond to certain thoughts goes a long way. You can't control what comes into your mind all the time, but you can control how your going to let a certain thought affect you. Just recognize the negative thought, accept it as just that, a negative thought. And let it go. Don't feed into or dwell on it, the more focus you give it, the more caught up into it you'll get. I believe positive thinking can benefit for some people. I don't agree with the above poster in the sense that it seems your trying to say that positive thinking is for weak minded people, and can't work for them. Different strokes for different folks. Your going about it the wrong way, it's not like you ignore it and go lalala I'm in my happy place, lol which might actually work for some people. But you can use logical positive thinking. Assess the situation rationally, and don't dwell on it. Like I said, just let that thought go and let your mind drift onto something else. If it's particularly distressing at the time, focus on something that does in face make you happy. For me, that would be my family, the gym, girls, ANYTHING. Use whatever just to get your mind of the stupid stuff.
