Help for a newbie trans

Hello, I'm very confused about what to do so my family can accept me as I am and I'm afraid they'll say something bad.

I also have doubts about the things I need to buy or do to look better.

And besides, I don't know what to do with myself right now. I think I'm stuck in a limbo where I just think things through but don't act in any way .

(Sorry the post was very long) :(
