This is my first time posting on this forum, you all seem very nice

So, about 2 months ago, I found out about ->-bleeped-<-, and some things started to make sense. But i'm not wholly sure I can go through a transition.
Basically now, I feel like a genderqueer, I dislike my body, and most things that define a "woman" don't apply to me. I dislike being called a "young woman" or anything referring to my gender. For example, I was working, and someone said "Watch out for the lady cleaning over there". It didn't feel like they were talking about me. My curves, my hair , it just doesn't seem to fit me at all. I'm not the caring, motherly type and the thought of having children scares me.
On the flipside, imagining life as a man excites me. I'd love to walk around shirtless and hang around with other guys, I'd love to be called "he" and "him" and have a boy name. So it seems that i'm a FtM,
But there are a lot of things stopping me from accepting this. I have a large family, a lot of which are religious. I worry about the amount of people that will turn away from me. I have a few friends too, which I'd like to think of as open-minded, but I just don't know how they're react if I told them how I felt. On a broader view, I think about anyone that has ever seen me as a girl and feel guilty, like i'm somehow misleading them.
As well as this, i'm only a teenager. If I did "come out" and start taking action to become a transman, only to realise it wasn't what I thought it would be, I think about how many people will tell me they told me so and I'm worried that even more people will abandon me because of it. Did anyone else have doubts like this? I'm especially worried about being wrong about this whole thing, as anything I will say on the matter will be so...final.
But there are cetain things about becoming a transman that I don't want, which confuses me even more (!). I don't want to pack, I don't want bottom surgery of any kind. If it makes sense, I want to be a man on first glance, but not completely change into one.
Any suggestions or advice as to what I should do would be greatly appreciated
And if this is all gobbledegook, forgive me. This is the first time i've admitted any of this to anyone.
