Pay no attention to those who would dismiss your feelings, my friend. Many of us feel that void at different times all thru the year...you just happen to feel it now.
My advice is to indulge yourself in something (preferably not self-destructive) which brings you relief and pleasure. Do you play music? Or write? Do it...and do A LOT of it. As for me, New Years has fallen out of favor for a variety of reasons - mainly, I can't tolerate a spitting headache and an upset stomach....that's just me, though.
One more thing....do something nice for someone. I don't mean spend a lot of money...just put yourself out there for someone. You will enjoy the rewards, regardless of wether you are with someone for the New Year or not.
Good luck,
