Sleepless

This is the 3rd day I didn’t sleep. Have been going to the library these days from night to early morning. I was feeling sleepy at the library but when I get back to my room, I can’t sleep. Maybe I am too tense, final exam coming soon.
By the way, my claim for Paypal Buyer’s Protection is denied. I was so angry when I knew it, cause I have sent the item back to the seller and Paypal told me the case is closed. An email was sent to Paypal and they told me the tracking number was not working, therefore they close the case. Must call up Royal Mail for an explanation. How can a 1st Recorded Mail like this. If I knew, I will use Special Delivery.
