I totally get the feeling of sinking into a hole with all this TTC garbage

I just posted basically the same thing yesterday

It must be contagious. I hope you start feeling a little better about it soon.
As far as progesterone, my RE only looks for >12 for a medicated (Clomid) cycle, and for unmedicated natural cycles, I think anything over 5 indicates ovulation and over 10 a really strong ovulation. I will check around a little more, I think there was a post about it recently. But I think your numbers are ok for a natural cycle.
