Help with basically everything.

I don't know where to begin. So I suppose I will start at the beginning of this brain wracking ordeal. For the past few years, I have felt like I didn't belong as my gender (M), but I never really done anything until a series of personal things that finally made me decide to care about myself more to look into it. I tested around with female pronouns on social media for a bit, and it felt.. right.. I suppose? If that is how I will describe it. I know this might be the path I want to go through, because I know I will be happier and feel better. But I am just so lost with everything. How do I break it to my parents, friends, how do I actually do it? I am scared, if i am being honest. I don't really have anyone to talk to about this, so I reach out to the transgenders of reddit for support. Please help me.
