Ive met a lot of patients who tell me they didn't sleep at all, and I was there all night. They did appear to sleep much more than they actually did - and aside from that, even just resting eyes closed (racing thoughts or no) still counts as at least half sleep. Ive also had the occasional night of no or poor sleep, woke up feeling drunk and still had to work ugh
Obviously, though, this level of anxiety is not tenable for you and you do have to do something about this. You reported similar all last year about your stress level. Like, medication, whatever change you need to make, you can't continue on like this. You said more or less the same 6 or 8 months ago and that it was only "for now" and yet... anyway, you are worthy of being healthy, rested, happy, loved, and not a ball of constant anxiety.
