I think I am a trash

I'm 27 years old but I didn't do nothing except computer games.
Only I have bachelor's degree of business administration.
But in Korea, I can't get a nice job only that.
so, what should I do? mm...
I'm weak as man. no job no job no job T.T useless person?
I got a job few weeks ago. the job is making film itself.
but I coulnd't handle 45kg film rolls. My weigh is 51kg.... how can I.
so, I quit the job and I think I am a trash
