I don't know why I feel like $#!+ right now..
I feel so stress out for no good reason..

Is it because of my health?
Is it because of my studies?
It is because of my grandpa's sudden gone?

My feelings are just simply unexplainable..
It's like watching a drama..
You don't know what you'll feel next..

Things just can't get any worst,
I'm having super bad flu and fever right now..
Why? Why so sudden??

I seriously don't know what to do right now..
I can't sleep without having nightmares,
I can't focus at all on my studies,
I can't eat, even if I do, it doesn't feel like..

Is this what stress is or is it just me?
What is happening to me?
