Hi Liz,
Yes, your story is similar, but all of our stories are. What is unique is how we handle various situations, our living environment, jobs, friends, family, and so forth. As we navigate the different obstacles and share our stories, others in similar situations can learn from what we did that worked and what didn't.
My approach to this is just as you stated, "I know that I am being true to myself." That is the most important part. How can anyone expect to be happy while denying a very important inner part of themselves? From there, I let that knowledge grow. If I am happy with who I am, does it matter if others are not? They are not living your life for you; only you can do that.
I take it another step further. Why should I even care what someone else thinks? If they do not approve, they are welcome to mind their own business. I stopped caring what others think for the most part. Obviously, safety is a concern. Just beware of those who may object violently and be safe in ways that women have always done: travel in groups (even to the bathroom), avoid sketchy locations, stick to well-lit areas at night, etc.
As you become more accustomed to this mental attitude and behavior, you will become more certain. As you learn about who you are, you will get to a point where you can explain it to others. People who do not experience gender dysphoria cannot understand how it feels, so they may have a difficult time accepting it. They have no frame of reference. Just explain to them that they don't need to understand, as long as they accept you for who you are. That is what matters. They can work on learning and understanding over time. Be open and honest if they have questions. Yes, it is a personal subject, but you don't need to give them a bunch of details. Make it easier to explain by keeping it simple. If it is simple and easy, then you become less anxious about explaining it, if that makes sense.
