As the girls said, I think new dosages or maybe progesterone could be the solution. The phenomena you are describing is quite common specially in high estrogen dosages: moodiness, anxiety, crying frequently, easily triggered. As you said, this is mainly: (number of things in your life) + (estrogen). You are more sensitive (for the good and the bad), so, if you got issues in your life (those that are disturbing you), the effect on your mood while being under estrogen is gonna be more severe and those things are gonna make you way more sad (as good things should trigger a happier response).
If you ask me, well, first find a dosage or a combo with progesterone to help stabilize your mood and then you will have something to work with. Second, well, begin working in solving those issues (passability, relationships, etc etc). Then, when you are done, prepare yourself to embrace the most valuable and remarkable truth in this existence: GIVING A F*** ABOUT WHAT THAT PEOPLE THINKS. Then, Nirvana.
And please, forget about "being trans enough", "deserving the HRT" or "if you are trans then your body accepts gracefully estrogen even administered in barrels". Come on, from that I have read, you look way too smart for that s**t.
