You might talk to your "dad".
He is probably sure this is a whim and needs to be "corrected"
Here is a resource that might help:
http://www.acceptingdad.com/2013/08/05/to-the-unicorns-dad/This is one of ways people are, one of the ways people have always been; you can't stamp this out of people. We know this because we all tried to, at one point or another, to one degree or another. There isn't a parent I've met who didn't play gender police for some period of time.
You might show in total and ask to be read or print parts.
here is another resource:
http://www.gires.org.uk/assets/DOH-Assets/pdf/doh-transgender-experiences.pdfThere are studies shown there which are by reputable sources. Its also explained with pictures.
Studies have shown there are differences in brains of women and men so a mismatch is possible.
There are even substances known to cause a higher rate of transgender people. They are off the market now.
Also transgender people have been around in all cultures so its not a cultural thing.
The brains of transgender people are wired this way before birth and there is no known way to change this.
Transgender people suffer from a condition called gender dysphoria, they expect a female body otherwise severe depressions can be the case.
Usually parents want their children happy.
The remedy is hrt and transition. Most people are much more happy afterwards.
Giving t instead of e usually increases dysphoria.
Threating you against your will is a criminal offense.
Nobody can make you use drugs.
There are even people dying because they refuse a blood transfusion.
Also you might have a serious talk with your doc.
To my knowledge they violated rules by giving medical information to third parties without consent.
You might look for an informed consent clinic in your place.
You might ask with plannedparenthood or look up some places, and ask some endos.
Usually the fees are not that high, and some offer sliding scales.
Also if housing is that high in your place you might look up lgbt places and ask there. Its possible they know places or have housing projects.
You might look for a trained gender counselor.
They might help explain to your dad its not a game you play and its serious.
They might also make clear to your dad that its necessary for you to try out hrt and how you feel.
This all is a step by step process anyway so its not a game but a controlled process.
Maybe you could tell them that you need to pursue this in order to live a happy life.
And that outcomes usually are much better if parents are understanding.
It comes down to that you are not what they have in their head you are.
They have an imagination of you.
But you have real feelings and it does nobody good to deny oneself to live other peoples images.
People are only happy if they do what they feel fits them.
Oh and transgender people are people like everyone else, not some twisted images people might have.
They are normal people with normal cravings.
Some people say they will simply be like their female twin.
