I think I might be transgender?

You are not alone. If this is how you feel you need to start talking to people. Do some research. Attend Gay Pride - there are TONS of transgender booths and people that want to help. If you keep this inside and locked away, it will only kill you inside. If you are a woman, be the best most beautiful woman you can be!

Yes, you sound very trans

I can't tell by that description if you're trans or not. Best go ask a therapist or councillor, maybe you can work through those feelings and become comfortable in your own body.

Yes, it does sound like it but get it sussed out by professionals.

Just having such thoughts does not make you transgender. No one here can tell you exactly what you are. This is something you need to discuss with a gender therapist and go from there.

Identity is different than who you hang out with. It sounds like you know yourself, and that you are a trans woman. Good for you!! The road to finding out who you are can be very difficult, but you have the idea and that's great!
You can look up online and in real life resources around your area to make sure you have a support group. Support is very important, you need to be around people who love, encourage, and accept you!
In order to feel more comfortable in your body, you should do research on transitioning and decide what you want to do. Websites/sources for trans people specifically will have a lot more information, support, and resources then someone off of yahoo answers.
You do not have to come out to everyone, that is your choice. You could pick and choose or whatever you want! You do not owe anyone anything, even if they are your family you do not owe them information about you. The most important thing is that you are safe and comfortable, do whatever it is you need to do to do that.
I wish you the best of luck and a group of loving supporting individuals! It is all going to be okay, you'll be great!
