I'm sorry to hear about your horrible day. I'll tell you what...go out right now and rent the movie "Office Space". Plus, buy a 6, 12, or 18 pack and chill out. And, if you're lucky enough to have the "resources", go find two chicks and...I'll leave the rest up to you! You know what I'm talking about man?! Ok...maybe my suggestion may not be the best, but it's a start! Things will turn around. Be positive and keep your head up.
P.S. At least watch Office Space. It will help.
Good luck
