Change

Have you ever had a period of time where you couldn't lift your spirits no matter what, always thinking that things would get better when you left here, but nothing changed after a change of environment. I feel that what I do is meaningless, I just want to do "what I want to do", but I don't even know what "what I want to do" is. I am afraid that my life will end in such a dull way, but I have never found an opportunity to change...
