Transgender Support Group
This community is here to support and help the large population of transgender people. If you or anyone you know identify as transgender, this is the place to share your feelings and experiences and speak with others who are going through similar things in their lives.

Like I said, I don't know if this cheered you up or not, but its the best I can do. I believe the only ones who cant transition are the ones who have not gotten informed, done their research and who choose not to (suicide, excuses to not, or other means of not doing it). I am also not going to lie to you and say everything will be fine and it will all be handed to you. It wont be handed to you, you have to fight for it. You've a lot of life ahead of you and while this second things may not be great for you, are you willing to really toss out all the time you have ahead to have it go right? stop worrying about the stages, stop worrying about the passing, stop worrying about the whole thing and go step by step and do it right, don't cut corners. you wont like the results if you do. Passing is more confidence than anything else, and if you observe there are tall women with very deep voices, so that isn't really a thing now is it. work towards the goal, stop trying to end it and do it right. research, you have the internet, find options near by. There are always options, you have to look and be willing to use them.
I don't have any great advice to give. Others have already done that. All I can say is don't give up. Yes, it is disappointing to have to transition later than you want to, trust me, I know. But, you are way ahead of many of us. And there is a lot more acceptance and support available today than when I was your age. Hang in there and don't give up. And don't worry about your height, there are many beautiful tall women. I hope to be one of them someday. (Might take a miracle.) I've never been a big fan of really high heels, anyway. You know where the true beauty will come from? From letting the real you out. Think of it this way, right now you are a caterpillar. You are entering the cocoon of counseling, hormone treatment, and whatever other procedures you choose, to become the beautiful butterfly you should be. Please hang on so the world gets to meet that butterfly.
Best wishes and hugs to you.
