Lately I have been getting more opportunities at work, and that's amazing, I'm excited! However, a co-worker of mine has become increasingly passive aggressive towards me. I can tell that it bothers her that I have been given more opportunities and she has been quite candid with me that she feels that she is being left out. She is significantly older than me and I'm not sure what to do. I love that my supervisor and manger see my potential, but I'm constantly thinking about how my co-worker will react when receiving a new project. I just end up doubting myself and my abilities.
