They all look down on me, but I am also unmotivated

No one supports my lofty ambitions, I can't even get ahead myself
Everyone mocks me, but I am also the funniest
The future is completely dark, so dark that I just sleep through it
If I had a bit of talent, I wouldn't be completely talentless
Gold will eventually shine, but I am just an iron rod
People who can defeat me, I don't bother fighting them
No one can use me because I am useless
People who love to laugh are lucky, because those with bad luck can't even smile
The strong never complain about their environment
But I am weak, I not only complain about the environment, I also complain about the strong
I wanted to cover myself with a blanket and cry, but I fell asleep instead
