Glee: (futurefic) Rachel is in her mdi-twenties and her career on stage is finally hitting its stride ... but she's been getting joint pain, she's having trouble memorizing lines, and she's constantly exhausted. The diagnosis is fibromyalgia. Preferably in the form of emails, text messages, and voice mails between her and former members of her high school glee club.

Bonus for an epilogue in which Rachel has adjusted her goals, gone after them like she does, achieved them.
