I'm very confused on the data

I've used a Garmin for more then 8 years now, and recently has been the first time I've been confused on the data. My HRV is tanking, my VO2 max seems ok. My load focus is balanced, even though it's on the very low side as I've been trying to rest to get my HRV back up. Yet my training status is strained. I don't drink or smoke. I was running 6km 5 days of the week, till recently. I haven't been sleeping very well, but that's been going on for years. I'm working on the sleep part of things. I eat pretty well, salad for lunch, yogurt or oats for breakfast, normal dinner around 6pm. In bed around 10pm. What am I missing?

Forgot to mention when my HRV goes this low I feel horrible inside, not like a cold or sickness, just a general overall horrible feeling.
