I have a bad feeling...

So my friend Nicole and I were taking a quick break earlier, and she told me that she needs to talk to me about something, but she's "afraid to say it." Now I'm really nervous that I did something wrong or she's upset with me or whatever, because I flat out asked her if she was leaving for another job and she said no. She said we'll talk about it later at dinner, and it's driving me crazy trying to figure out what it could be. I've told her some...very personal things...about myself, and I just hope to God that she's not going to ask me if I'm telling the truth or not. That will crush me and effectively end one of the best friendships I have right now. *sighs* I hate uncertainty about things like this...it's making me feel nauseas...
