That is a lot easier said than done. Many factors affect my mood and how I think, like my anxiety for example. I am feeling depressed right now but I am also feeling anxiety for some reason, so that makes it harder to fight the (correct) thoughts off.

Personally I wish there was some magical medicine that would make me not think, I would take that forever.

Let your actions dispel those thoughts. They'll only get worse if you don't prove yourself wrong. The solution for the problem might be actively seeking ways in which to affect the world in a positive way. Even if you don't feel like it, you have to try, or nothing will get better. That's how depression works, it just keeps growing and growing, like never-ending vines
