<human>: I've worked at my company for the past three years, and I work hard and do a good job. A couple of months ago, we hired on a new employee in our department, who was also hired on as a manager. She is younger than me and has a college education, which I do not have.

I am feeling jealous and insecure about my job. She literally performs all of the same tasks that I do and then some, and she is really, really good at it. She has a knack for it. She has also accomplished goals that we tried to accomplish last year but failed on, and everybody gushes over her work.

I am scared that I am becoming redundant and will lose my job. I'm also jealous of the fact that not only is she a perfect employee, she also undoubtedly makes more money than I do, being in a managerial position. My company never came to me with an offer of a promotion, they hired from the outside and on most days, we do the exact same tasks. It bothers me that in my three years, I've never been offered a raise but they hired her when they could have offered more work/hours to me. I was due to have a yearly evaluation at the end of June, but they have been swamped and still haven't gotten around to doing my evaluation. I feel very underappreciated. 

Has anyone been in a similar position before, that can offer some advice? Am I just being ridiculous? Thanks in advance.
