My friend got hired at the job I wanted to work at. What should I do?

I applied at a cell phone store in town to work in. I've been trying to get an interview with them, but they've been very neglectful on their resumes. My friend recently got a job at a salon, but only works there for 10 hours a week, so today she went in to the same phone store I applied in, got an interview and job on the spot! I know I told her about wanting to work there. Now I have to find another job elsewhere and I'm really upset. How do I tell her how I feel?
