Well, I don't want to sound glib, but I'm of the mind that there are two types of family dynamics, Dysfunctional and delusional. The whole Leave it to Beaver, Father knows Best and Donna Reed thing were a massive lie perpetrated on an ignorant public that was looking for normalcy after a brutal Depression and horrific War. So what you really have is an honest perspective of growing up in America...many don't or as I pointed out, are too delusional to deal with that fact.
As to your second point? Your Gender Therapist has no vested interest in you being Trans or Not. None. If they do, they're unprofessional and have completely violated their Hippocratic oath. So no, that's totally incorrect, totally.
At any rate, this is your life, your decision and your path. You have to decide first, who you are. You'd pointed out to me you're Jeanette in a previous post. You may not actually have that one internalized yet. If you do come to that conclusion and actually believe it, then you have to decide whether you can live your authentic life or whether you'll allow others to define it for you. It's only a decision for you to make. But first and foremost, you must know what you want. Without that, you're a rudderless ship. You can't get where you're going without a destination in mind first. I'm really sorry your people don't have your best interests at heart. Perhaps they feel they do, but that doesn't make it so. I hope only the best for you. That means I want you to get what you want. When you figure out what that is, you can create a road map and head for wherever that may be. All my best to you always, Jeanette!
