Have you talked to your parents? I'm not sure what the first step is when you try to transition so young, but I think your parents have to walk you through all the medical requirements, including just asking them if they can get you a binder etc. Are they supportive of you?

Bmachine has a point, without their support theres very little you can do. judging by responses i have seen here, not one F/M had full parental support, most all of them the parents were in denial. best wait until your on your own. dont think of self medicating, its very dangerous. the best you can do is talk to your parents very calmly, but dont start a war you cant win. no sense getting depressed either, just accept your situation and finish high school, plenty of time after that , by then you'll know what must be done. by then you may decide to be just a lesbian. believe it from me, Testosterone sucks the big one. wont have that crap in my body, rather die. just look how men can be such jerks, its the big T doing it.

I’m pansexual so I don’t looked at gender I look at personality. I have not talked to my parents yet I want to but I can’t bring myself to talking them it seems like everytime It doesn’t go as planned.

I wouldn't know about parents as mine were long dead by the time I was growing up, but it seems to me you are what you are and if you're truly transgender then nothing will change that including waiting a little while. I didn't transition as a teen, but once I was older and in a position to do so, I definitely got my T and went for it.

pansexual is a good chioce allows you a lot of flexibility. you can chose the gender you like best. its all mood dependent, you can be the best of both worlds, love your choice. take your time telling your parents, no need to rush, you dont need HRT being pan. Good luck.
