Hello Staceyjade
A quick hello from me, someone your Mum's age who also has palindromic rheumatism on her records back in time

Luckily I was probably early 40's by then.
I do have some understanding of how you feel though as my youngest daughter, (19), was diagnosed avascular necrosis in her LT hip and RT shoulder at 18. This was caused by chemotherapy and high dose oral steroids which she had at age 16 for 2 and a half years.
She had surgery on her hip sept 2016 and a new shoulder this January. Her self-esteem isn't great either and finally she has taken the first step to getting help by seeing the Dr last week. She is staring talking therapy very soon.
She also has an interview for a very part-time job (she still sees 4 different consultants so time is restricted) next week. I got the impression you do work for some reason??
Lastly YOU are young attractive and funny too I bet - else your bf wouldn't be with you!!
Keep talking it helps
Take care
Toni xx
