I think that at the end of the day your happiness is the most important thing. Your situation is complex though because you have to consider where you will live as well, but do not remain somewhere you won’t be happy. If you will be happier with transitioning then do it and who supports you will support you. I know how difficult it is to live in a house where you aren’t accpeted and have to hide who you are. From personal experience I think that doing what makes you happy and feel more like yourself and facing whatever hurdles come along is worth more than remaining where you are being someone you aren’t and experiencing such sadness. Wish you best of luck!
