My fingers are crossed for you on the job thing. Let us know how it goes!
I have also had friends that have not been supportive. I simply don't talk to them about the stitch anymore. I used to. Now I don't, if they ask, I just say "things are progressing" or "nothing new" and change the subject.
As for transitioning from talking to her to the above...or hopefully resolving it here...something along the lines of "I appreciate your advice, but I also really need your support. This is my M and my decision to make, and I would really appreciate your unconditional friendship please." If that doesn't help, then you may have to put your R on the taboo subjects list with her.
Outside of this BB, there are very few people I regularly talk about my stitch with. Two of my friends I do, 3 I've had to stop. I don't talk to my parents, although I do talk to my in laws occasionally. It just depends on the person and how non-judgmental and supportive they will be.
