In basic Psych, one of the things we are taught to look out for is the negative triad...
"I suck, everything sucks, and it's always gonna suck!"
When you get caught in that trap of negative thinking, you lose all the pleasure in life. Some people have to retrain themselves to think more positively or else they wallow in a mire all the time.
Try thinking: I may not be satisfied with my life at the moment, but I can still find small things to enjoy and I can set positive, reasonable goals.
