One thing to be aware of is that transitioning reduces dysphoria, and not just by a little.
I’m well into my transition (currently on the waiting list for bottom surgery), with 1.5 years of HRT behind me and all the legal stuff completed and… I don’t feel all that much dysphoria these days… Because: Why would I? I’m beginning to really like how I’m starting to look these days and can even look at pre-transition pictures without issue and go: “This was me, can you believe it?”
The earlier you are into your transition, the bigger the focus on being trans can be, until it eventually turns into less and less of a big deal.
Self-doubts early on are btw. so common that I would frankly just consider them a symptom of gender-dysphoria in their own right.
And to be clear, I can’t tell you what you are, but I can tell you that what you describe sounds like a very common experience and nothing to worry too much about.
Have you even read that Wikipedia article that you yourself linked?
