Afraid

For the very first time, I'm afraid on it.
I felt reluctant to go back to university.
Guess what??
I just feel that..
I'm really a useless guy...I don't know how to do things..
I used to do things well, but now, I have doubts on it...
Now everything is against me..
He, She, They, You...
everyone is against me...
So what should i do?
What should i say?

I don't know.
I'm just...afraid...
