I have a few thoughts.
1) Your blood work after 10 weeks of hCG still shows lowish testosterone and really low estradiol. That's why you aren't feeling good. I don't know your medical history so the advice I can give is limited. Keep that in mind. But in general it seems like a good idea to try and do a HPTA restart at your age. I would recommend using a higher dose of hCG for this AND using clomid or Nolvadex too. This will give you the best chance of getting it going again. Keep in mind that it could take months.
2) Now that you are injecting testosterone, it would be helpful to see your blood work. This is just a hunch, but there is a correlation between estrogen and migraines. My guess is that your estradiol may be spiking up while on TRT. You aren't taking an aromatase inhibitor. What is your approximate body fat percentage? The high estradiol could explain your other symptoms too while on TRT.
Why did you stop seeing your primary care physician for this? What was the diagnosis when your doctor prescribed TRT for you? Do you have your blood work from back then?
There is a link below in my signature that will take you to a FAQs thread. There is a section in there for TRT. I suggest reading all of that.
