I lived alone for 10 years and have spent many new year's eves without a date, sometimes even all by myself because I didn't want people feeling sorry for me... in the end I decided it was no big deal. These "special" days are just special because we decide they are (as others have been saying before me in this thread). Once you look upon them as ordinary days that, in this particular culture and also because of commercial reasons, are made out to be special, it feels different.
My advice: book a spa treatment, massage, pedicure, whatever you like, get a nice half bottle of wine and your favorite deli dish, rent a great movie (preferably a funny one) and LOVE YOURSELF. It's not pathetic, one should actually do this more regularly !
