Thank you to everyone who answered my questions (update)

I wanted to thank the people who gave me practical advice. This is my first time dealing with any of this. I feel calmer and more organised now. What would help newcomers most?

Thanks for writing this out. I went through something close to it last year, and it settled down once I kept a simple log of every call and form.

Glad it helped. Reading how others handled it got me through my own bad weeks too.
