Set your alarm clock with these messages:
I'm a big boy/girl now, so it's up to me to get out of bed.
Life can be shit, but the alternative is far worse.
The world is full of lonely people...especially if they don't get out of bed.
It's up to me to help myself.
The world is full of people waiting for others to solve their problems, I don't want to be one of them.
It's not a really bad poem. And the sentiments are probably real for you. Keep writing and communicating. And BTW, the usual reason why 'no one knows' is because you haven't told anyone! I know...I've been there.
Looking forward to reading more positive poems
