Plenty of uncertain

Not pleasant, like I have tons of stuff in my mind but I cannot express it.
Admit what I have done wrong and I try to make it right.
But it seems like not enough.

I'm out of my mind.
Try to take the opportunity to make everything move forward, yet I still cannot give myself 100% full marks.
There are mistakes everywhere.

I'm happy to take the chance, just make me special among all.
I'm going to miss you.
Yet, it likes the destiny.

I ask for minimum requirement but you give me lesser.
Less than what I expected.
I do not think that I am a high demander, but I expect for fair treatment.

How is this gonna suppose to be? :(
