Dunno why.

Dunno why for no reason I can't concentrate in my studies at school.


Dunno why when comes to night I feel like so tired.


Dunno why for no reason I can't finish my homework.


Dunno why I can't find the information that I want in Internet in order to complete PJ's work.


Dunno why I feel like I had changed to another person.



Am I?
