What happen??

I just want to have a reason,
why things suddenly turn down??
I did nothing,
why must the thing changed so bad??
Can someone tell me what happen?
I set a deadline,
but the closer to the deadline,
the more sad I am...
I am totally collapse now...
I am afraid I must be give up something after deadline,
I really don't want to have that ending.
I tried so hard to be brave,
and pretend I am happy..
But I can't stop my tears.
What should I do??
Should I cancel the deadline>?
Should I clear the things right now?
What should I do??
