I agree--it can be very confusing.
Good thing we can all gather here to ask our questions and help each other through this Jungle!
I started out on Estratest HS after my surgery. I stuck with it for 7 months or so and then switched to all compounded hormones, then evetually over to some compounds and some pharmaceutical company produced products. It can take some trial and error and time and patience to find the right hormone therapy, so hang in there!
I use compounded testosterone as part of my hormone therapy. Initially I used it daily but after my levels built up, I found that using it a couple of times a week was sufficient, and now I can use it once a week at most and still get the benefits of it without the side effects. I think it would be worth considering using it at some point for part of your hormone therapy if you don't feel that Estratest is right for you. I think you should have your free and total testosterone levels checked first to be sure you're actually deficient in that hormone.
What time of day are you taking the Estratest? You might want to experiment with the timing of your pill to see if that would help with the insomnia. Another thing you might consider, once you feel balanced with your hormones, is adding progesterone. It can help some of us sleep better and help with feelings of anxiety. It also can help breasts which feel sore from too much estrogen.
It's easier to work with adding just one hormone at a time so you can see how your body reacts. That's where that journal can really come in handy. Sounds like you may be putting that gift to good use!
