Hello,
I think you'll find a lot of support here. I would be careful trying to transition at home with unsupportive parents. How much have you told them, if anything so far?
They may surprise you if this has been a secret you've been hiding. It could ease their minds if they thought you've been acting strangely (which in turn can lead to an erosion of trust). Remember, they had hopes and dreams for you; seeing you graduate from school, getting married, having children of your own, etc. Transitioning kinda squashes all that without some serious planning.
Or if you have come out to them before as TG and the reaction was negative AND you pursue transition anyways under their roof you could end up sleeping on friends couches or worse - the street.
I did have more to say but now I have to pick up my own child from school.
