Some more ideas-
in the past, there was the concept of an every day test (English word?) where during therapy you had a given time, like one or two years, during which you were free to experiment and see how you felt. It's not the worst idea if someone is not sure how to proceed.
Like was suggested, you could set boundaries in which you explore stuff. A male day, a female day, a genderqueer day etc. Make sure to have "genderfree" days a lot too. You really need breaks in between all that obsessing ;-) we all do the obsessing, but it shouldn't overwhelm you.
Talk to an endocrinologist about your hormone dosage. Maybe also to a gynecologist. It's a bit of a challenge to find open-minded and experienced doctors and therapists, but hang in there. I searched for almost a year, but now I have a good team.
And really make sure that you have nice experiences in other areas, and take good care of yourself (regular food, sleep, free time, sport etc).
Just avoid situations that trigger dysphoria. If looking in the mirror makes you feel bad, don't look in the mirror and so on. Don't get OCD-ish with that though, just try do it naturally, as you would not wear your tightest trousers just after christmas ^^
