Happy trans day of visibility!!! To those of you who may not have accepting families, just try to remember that where you are right now isn't permanent. It may still be a long time, but you will be able to get out of there.
And if you've still got a while until you can leave, my advice is to think about and plan where you'll go once it's time. If possible, save up as much money as you can so that you'll have enough to still afford things when you go. I would also recommend living with friends or roommates (to lessen expenses), moving at least to a different town/city if not state (to make it harder for toxic/unsupportive relatives, family members, and family friends to track you down if they might try to), and cutting off all contact from toxic/unsupportive relatives, family members, and family friends when you leave.
