@[email protected]In July 2020, I started feeling constant, acute pain and was later diagnosed with #fibromyalgia. I've been in pain 24/7 since it started.

Account is locked; a significant fraction of what I post is followers-only. Got a blank or nonsensical avatar, no visible activity, no pointers to your identity? I'll ignore your follow request. I might choose not to accept it for other reasons, too. 🙂
Sometimes I ask questions here. When I do, I would ask you to please reply with your own thoughts, not an LLM's.
