I'm glad to hear you've done well with the AAs. I'm on spiro and very low dose estradiol, mostly for the mood changes, and it has been great. Similar to you I was needing to take care of the dysphoria, which it did immediately, while waiting for a few things in life to clear up before going all out on transition.
One thing to keep in mind is that an AA only isn't a good long-term situation, as the body needs sex hormones for bone health. You'll need T or E or osteoporosis becomes a big problem.
