Friendships and trust

[Tangled Web]

Well I recently handed in a resume of a friend of mine to my work. She is considered a close friend to me. She knows about my "others". I am scared now though. Oh and she got the job.
My work life and my personal life are completely separate from one another and now she is a piece of my personal life coming into my work life and it is freaking me out. I am NOT the same person as I am outside of work. Work is totally different. I have explained that to her, but I don't think she understands the importance of it to me. I know I have to have another conversation with her about this but I don't know how to right now. I want her to work there but then I don't. I don't know how to trust enough that she will not blow the lid off my life completely and tell my coworkers about my life.........or say something to me in front of others that will cause them to ask questions. I don't think she would purposely do anything to hurt me. I am just very worried.
