Getting a C-FIS

Not quite sure if it's the bad weather, or the season, or start of the 3rd term (but definitely not the time of the month this time!) that is making me feeling really really LOW......

On top of that, today I decided to watch 'How to lose a guy in 10 days' coz I saw channel 4 advertising it on tv and it was really funny (mr. sniffles). It was hilarious for 3/4 of the film (just love the perfect display of an unreasonable, in-love, obsessive, super-girly psycho girlfriend) until it got all serious and that fairytale happy ever after ending gave me a chick-flick-induced-superlow (C-FIS)

C-FIS is a new condition where there is a sudden feeling of emptiness, develop only in individuals where they are reminded about those special moments of the past that were lost due to unforeseen circumstances.
Symptoms of C-FIS include: tearfulness, loss of motivation and concentration, comfort eating and the feeling of hitting rock bottom.
Treatment: I wish I knew.
