Who Will Catch Me If I Fall?

I'm sorry that I'm crazy,
And I don't know how to behave;
I feel like everything that I say
Is just a big mistake.
Could you pull me closer,
And tell me it's not over?
Do you really love me,
Or should I just go away?
There are countless stars in the sky;
I wish I could shine so brightly in your eyes.
But I'm one in millions,
And maybe you don't notice me at all.
I keep on tripping;
I'm always slipping.
Who will catch me if I fall?
