Hi Revan,
I totally understand what you are feeling at this time.
I would like to answer you two things :
First, you cannot control the other and their reactions. And probably, more you try it, worst happen. With transition or not, with hormone or not, conflict can happen with kids, parents, family, friends... but i am pretty sure that it is not because hrt, you know.
Second, I think, in life, for everybody, we have to take care of ourselves and do things that make our happy, because, if you, you are happy, it is the best chance to give happiness around you. We are responsible of our happiness. If another person is not happy, you cannot blame you, of course not, never : it is the choice of this person.
I wish you the best and i am pretty sure that with love and love again, everything can be just fine.
Take care of yourself and of your family,
Hannah
