I'm Stressed !!!

Assalamualaikum...

Back again...
I'm busy right now. Still in the office doing building submission drawings.
I've noticed that I'm stressed out lately. The signs are:

1. Cannot sleep even though I'm so tired. My eyes are shut but my brain refuse to relax. As a result it's been 4 days that I slept at 2 am and wake up at 6.30am. Go to work at 8.30am and go back home at 10.30pm.
2. Feeling faint all the time.
3. No mood to eat.

Sigh...when is this work going to be over.
Need to have a long holiday after this...
