I've found that being right is overrated. I have an extensive philosophical education and am probably right on the money as it concerns reality in many ways.

I find that in terms of our psychological experience, well-being is more important. Which might even mean acknowledging wrongdoing that you may have caused to others, or it might mean letting go of that pain or guilt in a healthy context.

The likelihood is that you're not as responsible for the outcome of your life as you think. We perceive reality through the lens of our mood which in turn shapes our beliefs. So while your low mood might be increasing your ability to be skeptical (especially of yourself), it prevents you from also seeing or recalling positive events or cognitions as well. Your brain is essentially just doing its job when it constantly criticizing you, but just more so due to depression.

Focus on what you can manage and accept what needs to be accepted. Go for a walk or hop on a treadmill, or download the app "Headspace" and try Meditation out for 10 days to see how you like it.

The honest truth is that you don't know the future, you don't know if you'll turn it around or not. I find that assuming that I will, and only focusing on small short term goals does wonders for my health. These cognitive cycles will only spur on more downward spirals and act as a self-fulfilling prophecy.

As I have heard it wisely stated, "let go or be dragged."
