I agree with the poster above. I also beleive it is entirely possible that the harder you play the harder you fall. Certainly seems this way in your case.

Play releases endorphins and other hormones and neurotransmitters which cause pleasure sensations. When they go from the system they cause withdrawl (bear in mind most drugs are variants of hormones or neurotransmitters, work out the rest for your self...). The more of the drug you take, the higher the pleasure and the greater the come down...

Hugs may help...
