Internalized transphobia is something I deal with myself, so you aren't alone, if anything else remember that others know how you feel and that a lot of them reached a happier state of being, and so will you. *hug*
Being trans comes in so many zany flavors, I had to deal with a lot of "omg this is making me feel weird its like some of them are forcing it" internalized stuff too. At the end of the day they either are just that way (think of every time a cis man or cis woman fits a trope of like.. 'valley girl' or 'gym bro', and realize that kind of 'exaggerated personality' feeling isn't exclusive to trans) or they aren't and they'll figure it out on their own, like anyone hiding behind a mask trying to figure out who they are.
I'll be the first to admit to internalized shame. My brain is a hotbed of activity with it, to the point where no matter what angle I turn on some days I'll be mentally devaluing myself. I'll tell myself I'm just faking it. forcing it. That my brain is broken. And then devalue my neutral state for being "not feminine enough to be trans", then I'll start panicking about being wrong, or telling myself to go back because it was better before (it wasn't. I couldn't look in mirrors because they made me angry. I would get literally panicky and upset about getting my picture taken because I'd have to see it. I had the same clothes for 5+ years and couldn't stay in one store trying on clothes because i hated it, so much. I showered once a week, once every two weeks, because I didn't care. I've put holes in walls and watched myself hit the drink way too hard to be healthy.)
I didn't start this path to become a valley girl, or to start the worlds biggest shoes collection, to go on a "sex in the city"esque shopping spree or ANYTHING like that. It was never about becoming that. I'm actually a nerd who loves drawing, videogames, DnD, and go. I did it because of the reasons mentioned above, and because the idea that maybe... MAYBE things could be better if I had a body I wanted to see in the mirror... That maybe I was able to feel like I was worth showering everyday, or to love myself the way I wanted others to love me. Those ideas stuck in my head like a burr and at least partial transition with hormones was the only path I could find to take me there after years of just trying "dressing up now and then" or "wearing makeup while also wearing guy stuff".
nor did I spend my childhood years endlessly pining for a genderswap; there were a good few instances of being entranced by what the other gender does, but as a kid these feelings felt more natural and my childhood was otherwise unremarkable. Because of these things, because my discoveries came in my adult life, they came after I had a lot of time to sweep things under rugs, to build up walls around "trans" stuff thanks to daytime TV talk shows like Jerry Springer and friendships forged in tasteless humor, and the result was treating everything trans-related (honestly even going to trans help sites, at first) as an "alarm bells" situation that seems somehow "wrong" despite it being no different than seeking help for depression.
Take a deep breath, slowly exhale, and center yourself. You are not alone.
