It's not just the negative thoughts though. 

How do you deal with the "bad feeling" that exists constantly, at every moment of being awake and conscious?

Yeah, it's a complex issue that sometimes doesn't even have a cure.

Personally, I'm unable to find happiness in anything that I do. Things that I used to enjoy are no longer fun. 

Thoughts like "why keep going if nothing brings you joy" are therefore pretty logical.
