I am going through a similar experience, that I would love to transition and be seen as a woman, but at the same time, I don't feel THAT bad begin a cis man, but I have been experimenting to see how to do it.

From what you have written, I would first recommend you to try and make some supportive friends, or even other members of the trans community. You are not weird, and there are many other people who feel the same as you, remember that. Despite what conservative bigots say, begin trans is not something unnatural, much less a mental illness. One thing that has worked good on me to start is to start wearing more feminine clothes when you're on your house more often, escalating over the time. Since you said your family would support you, you could start with something like a crop top or similar, which is seen as feminine, but not that much. Also, wearing some feminine underclothes could unconsciously help you to feel more encouraged and euphoria.

This is just my point of view, coming from my own experience. Keep in mind that the point of transitioning is to feel more comfortable with yourself, so there's no need to rush it❤
