I'm glad that you feel safe talking about your experiences here. This space is for questioning people as well, and you are absolutely welcome here.
It can definitely be hard to feel feminine when we can't see past all the things other people say exclude us from femininity. I can definitely relate to that a lot. It's like we're locked out of half of human expression just because other people decided we couldn't present that way. Thoughts like that were very prevalent for me during a lot of my life. Being gender non-conforming is hard.
I did want to respond to a few things. Firstly, you don't have to have extreme discomfort/dysphoria in order to transition or to want to transition. A lot of transfeminine people relate to a feeling of passive apathy about their bodies and presentation as opposed to strong persistent dysphoria. There's no real qualifiers for wanting to transition. If transitioning/presenting more feminine makes you feel happy/euphoric, then that's what matters more than anything. Being trans is about joy. It's about feeling a sense of connection with who we are and the image we present to the world.
Second, there's no rules for being trans or transitioning. There are some transfem people who will always go back to presenting as a man (boymoding) when they're around family or friends or at work. It's about what feels comfortable or realistic to you.
Thirdly, there's no age limit to transition. And related to that, I have met passing women who pre transition very stereotypically fit the conventions of masculinity. Feminizing hormone replacement meds are amazing. And I've met passing women who didn't start to transition until their 60s. That's not to say that HRT (hormone replacement therapy) is magic that will make anyone instantly pass, but that it's far more complex than it seems at first. It changes a lot about your body. Your starting point does not entirely relate to what HRT can do for you.
Lastly, I want to recommend reading the gender dysphoria Bible. It's linked in the community sidebar. It talks a lot about some of the things I mentioned above and really has a lot of answers to questions about what it is to be trans or to want to transition. I really do encourage you to read it. It helps a lot of people understand what they're feeling a bit better.
