Poor thing..how mortifying and scary.
Please encourage her to see a doctor. I have a mother with a laundry list of health issues but she will not go to the doctor. "Oh...doctors don't know anything and they are just pushing drugs." Sigh....
Now she has put off so many things that her symptoms have worsened. I really believe if she had caught things when they first began then she wouldn't be in the crisis mode she is in now. She doesn't like to face reality and get bad news...so she lives in denial. It is so frustrating...but overall my heart aches for her.
I know that it is scary to have to face something and maybe get a bad diagnosis. But...she might have something pretty simple to fix in the beginning stage. Sounds like this JUST started happening...that could be a good thing if she addresses it quickly.
Suggest to her if you can pick her up and go with her to the appointment and then go out for a yummy lunch afterward or a movie. Give her something to look forward to that day, be a support and then blow off stress afterward together.
You sound like such a kind and compassionate gal pal!!
