On not panicking:

With regards to finishing up major assignments when you are sleep deprived and just want to go to sleep:


Also:
I must not fear.
Fear is the mind-killer.
Fear is the little-death that brings total obliteration.
I will face my fear.
I will permit it to pass over me and through me.
And when it has gone past I will turn the inner eye to see its path.
Where the fear has gone there will be nothing.
Only I will remain.

So mote it be.

Edit
Also note that this assignment is graded pass/fail (worth only five per cent of the final grade) and chill the fuck out. Make sure all the elements are in there and hand the fucker in.
