How would you deal with feeling betrayed by life?

After months of intensive psych and babble (psychiatrist), I’ve come to find the answer to why I’m so depressed and angry all the time. We recently discovered that I have sort of a discontent with the way “Life” is. Not my life but all life, as in all the pieces of the puzzle that makes everything of EVERYTHING function. Specifically, how I spent all 27 of my years trying to be a decent person and getting treated like p00 p00, accomplishing nothing, and coming in last at everything (relationships, financial, happiness, etc.). It seems like all the bad people get everything they want or something that they can settle on, while the good just get screwed. This is a very complex problem (the words of my doctor) and I really have no way or direction to go from this point, I feel like I’m just going to die alone because I played by the rules.
