Growing up?

My impression of Polytechnic was freedom and fun.

I still remembered how excited i was to come into poly, to be in a whole new environment, experiencing new things, make new friends...  

But no thank you. 

I missed how things were like in the past. I wasn't so 'cold' and unfriendly. So unhappy.

I thought i was the only one who thought this way until i met one of secondary school friends and we kinda talked about it. 

Why are we becoming more and more unhappy as we grow older? 

Is this part of the growing up process? 

How i wished time could stop, i don't wanna grow up.
I'm so tired and drained out, every single day. 

P.S: I'm turning a year older in 4 days
