>Lolis aren't bitter all the time, too.
That's because they are children. Their life is a blank canvas. I was energetic when I was a child, too.
>If you feel bitter most of the time, you should change something
It's not that easy to change, often not even possible. Like how someone who is out of shape lacks the energy to exercise or someone who is trapped in a dead-end job lacks the work experience to do anything other than what he currently is doing.
>A person with a depression is neither true to himself if he/she finds excuses why changes are bad.
Your life choices up to that point are responsible for your position in life. Like I didn't take my education as seriously as I could have, getting mostly average grades, and because of that I couldn't get a college education, which demands excellence. Being true to yourself means owning up to those choices and realizing that it's because of your personality that you are where you are now. The guy in the comic isn't true to himself because he blames someone else for his own failings.
