Hi Ellie. I worked for the federal bureau of prisons for 11 years and I'm absolutely certain we are prisoners to lupus. That trapped feeling you describe. Inmates can't go to the rec yard when they please, they must wear certain clothes, and Lord knows they get weary.
Sounds a bit like us.
I'm very proud of you for taking that 20 min walk even though you had to pay for it. I think we all do more than we should on occasion knowing we will flare. We try to grab every bit of a normal life we can. BTW I've also bawled on the phone to a nurse. You're not alone Sweetie and vent all you want. We are here to listen. Love, Butterflake
