Hey, NIcks NOse

I do understand resentment and bitterness. My situation was opposite ,but with same effect. I am quite younger then my colleagues,though had similar education and training in a good facility(started right after school and no social life). When I started working I was disregarded as a professional because of age,gender.I had to prove my professional choices right and left,finally, they accepted and now respect me professionally,but there is resentment on my part and some anger for discrimination,which I am working through just by enjoying what I do ( i know I am not going to be chosen for advanced positions anyway).
Just let it go,or if you are bold enough talk to you administration to understand the problem
Best wishes to you
