Saphie - the alcohol is your solution -- so what is your problem? Think about what is causing the anxiety or what ever is making you feel incomplete (such that you think alcohol can fill the void).
Focus on fixing the real problem. Yes, celebrate - but celebrate by being good to yourself.
When I feel like you do, I go and read the Friends and Families section of SR. It gives me perspective.
So, eat that funnel cake (heck eat two). Just don't expect that alcohol will do anything but make you worse off.
