I understand and appreciate the message though: "Think positive". I don't believe positive thinking can authentically fix anything because pretending to be happy solves nothing. Pretending to be happy doesn't actually make me happy and just causes me to suppress what is really happening at an emotional level, which in turn creates more complex problems a few months or years down the line.
However, maybe pretending like I'm happy will give me just enough fake energy to do something, and in doing something will lead to real energy that will enable me to actually do something. So, I will try and I will let you know how it goes.
