I messed it all up....?

I feel like **** now... there is a girl i really like at work; she always had a boyfriend so it killed me that i could not be with her. I said to myself "if i really do like her then i should just let her live her life until she becomes single again" after all that time she finally breaks up with her boyfriend and not more than a week goes by and she is taken again... I feel like **** for not making my move. We went to a party (work related) and me and her flirted alot and were "touchy feely"(i was kinda drunk). Now after finding out that she has another boyfriend i feel pretty depressed, i fell in love with her personality and her cuteness is the icing on the cake. I feel like **** and just want to sleep all day. My friends and i are getting together tonight but i think i just want to get drunk so i can numb this pain....I really like her alot and it brings a pain in my heart that i have to see her at work and pretend like everything is alright. I hate my life right now.
