I enjoy going out on NYE, but there have also been years where I've stayed home or gone to another person's home and had a great time as well. It can be as low-key as you want it to be. Invite some friends over, enjoy some champagne (or not if you don't drink), put out some good food and watch the celebrations on TV! New Years Eve is fun and there's no need to miss out just because of the phobia.
