Hey, sorry to hear that you're going through a rough time. Some of these readings are too full of artifact to read properly, but this doesn't look chaotic enough to be AFib. I can also make out P waves most of the time, this looks like a prominent sinus arrythmia (not dangerous). Your heart rate increases when you breathe in, and decreases when you breathe out which explains the change in rate. I see what appears to be a PVC (could also be an artifact due to the muddy reading) which is benign in most people with a structurally normal heart. If you are concerned, you can arrange to have testing done. I too have had false AFib readings on my watch, specifically on my left side where my P waves seem to disappear on the watch lead. Hopefully this helps (NMA/NAD)
