Wondering if anyone else out there gets depressed after an eventful weekend. My girlfriend threw me a surprise b-day party this weekend and invited a bunch of friends and family to visit for the weekend. I was ridiculously surprised and had a great weekend. However, now I am ridiculously depressed and don't know whether to apportion it to the drinking, lack of sleep, and the fact that the weekend is over or if there is some other reason. But I have noticed this has happened to me in the past after eventful and exciting weekends. Any thoughts?
