HRT effects take place over a very long period of time. Give yourself a chance. I know that you want to go from point A to point E but you have to give yourself time to get there.
Nurture yourself. Work on your mental health, take good care of yourself physically. Like you will get the best results of HRT if you are in the best place otherwise to receive them. Its unfortunately not something you can rush. You must gradually work towards it. If passing really really matters to you then work on your mannerisms, voice train, practice with makeup, develop your fashion sensibilities and invest time in your presentation. All those things take time to develop too, and its also totally valid to not bother with any of it. I am a very conventionally feminine woman and those things have mattered to me so I have worked a lot on them. It all takes time.
And to echo statements in other comments, you’re never too late to transition. You look really pretty and you will absolutely have great results with time. Try your best to be patient with yourself.

As an Autumn, I think you should go with Autumn. It suits you and goes well with your first and last. Plus Autumn is just a cute name in general, though I may be biased haha
