Anything on the screen is probably made to inspire us with positive messages, but we know that reality is not that sweet. I would have the same thoughts even if I didn't have any experience like you.

As for the cynicism itself, I think you need to give yourself time. I try my best to look at something from many sides. I try to be as logical as possible even when my heart goes crazy. This world has positive things in it, and I want to believe that one day I'll get to see them too.

What have you tried so far?
