My friend is acting really weird around me!?!? (10 Points)?

I went to Australia with my family for holiday and I went to a Chris Brown & Rihanna concert with my best friend who lives over there. Anyways there was this comp to text in this code thingo to win a meet and greet with CB after the show like backstage. We both did it and my friend actually won. It was my birthday the next day so I told her to get a clip of him saying happy birthday to candice (me) :D but she didn't get it. She got her pic taken with him and he signed her ticket and she got an autograph for me but not the clip. She said his body guard said no and so she said "ok". She did'nt even try....I feel like my birthday is ruined because I love Chris Brown....my friend had always been like "I love his music and he's such a good dancer and blah blah blah".....what do I do? I went off at her and now she isn't talking to me. She said she went out of her way to get an extra autograph for me and that I should be happy for her that her biggest dream came true. Which I kinda am but I should have won....as a good friend she should have offered to let me go instead but she just said "will you be ok waiting here?" (with some people, of course). She was so excited and she actually screamed and cried when she found out. ARGH. I've messed everything up because I yelled at her and stuff. She's acting funny around me now. How do I fix this???
