Dear OP,
I have read all your posts and I understand what a difficult situation you are in. That's because I had a friend who was in a similar situation, some years ago. (And those of you who say the OP is a troll, I'm 99% sure she is NOT since I have seen multiple similar cases over the years, having been in the trans community for over a decade now.)
I understand how it's great for everyone to say how you should move out and leave your parents behind etc. but that's not always easy, even in your 20s. Culturally, some people are very close to their family, and it's very hard to break ties. Every important tie broken in life represents a source of grief, and women at the beginning of their transition have enough anxiety and issues to deal with already to need so much grief. For many people, rushing into making such drastic decisions like moving away from family whilst in such a vulnerable state can lead to future setbacks.
As for unsupportive family, I guess that means your transition needs to move a bit more slowly, maybe via a unisex state from what I have seen with others in similar situations. If possible, you may dress up when away from family, and revert to unisex presentation when with family. My experience suggests that many unsupportive families eventually turn to a don't ask, don't tell state over the years, and the relationship otherwise may not be that harmed. The important thing is not to give up, that is the most painful in the long run as you found out after detransitioning earlier this year.
Your hair needs to be more feminine for you to pass. Also, you have a long face, which means a fringe may be of help. I don't exactly know the situation with your hair, but I think a fringe clip-on piece may be helpful if your hair can take it. It might turn your hairstyle into a short, feminine one. Other than that, even if you have to use unisex clothes, adding feminine accessories, as I saw you did back in some photos last year, really helps. Many trans people on forums insist that you should go all out with dresses etc. even early in your transition, but I don't think it's a must. Also, don't mind too much about what some trans people say - they probably only started a year before you and play the expert. I have seen too many of these people over the years.
