Sadly, as the saying goes, you cannot choose your family. Some families are supportive of trans people but many others, for any number of reasons, are not. My mother has been very accepting and supportive. My father was angry at me for over a year and while he probably still is he is prepared to talk to me. My sister and brother have barely communicated with me in two years, their young daughters (my nieces) don't even know they have an aunty. The one person in my family who I expected to be the most supportive, my sister, has been the least. It is heartbreaking, I know, to have your family treat you like some kind of criminal. From my point of view, I am always open to my brother and sister properly reconnecting but until then I just need to put it out of my mind as it is too painful to dwell on.
