Should you take abuse from your family if you have nowhere else to go?

Sorry, kind of dumb here but. In a theoretical situation, if a 20-something trans person lives with a family of narcissists who doesn’t support them, is this the best option? In this theoretical scenario, the Nfamily, after feigning support to shut them up, will turn around and tell the trans person that they will only ever be the gender they were born as, and generally treats them with disdain and outright hatred. This theoretical trans person has come out multiple times as a young teen, their family promised to get them help, and then ignored it multiple times, hoping it would simply go away. This theoretical person is punished when to be treated more kindly by their Nfamily. In this theoretical scenario, the trans person has given most of their money to their family for help on mortgage payments, rent, and drug money. This trans persons money is now the family’s money, to pay the family back for the costs of their childhood. This theoretical person has nowhere to go. Their family plans on leaving the trans person homeless if they keep rocking the boat with being trans and continue to retaliate and express discontent when verbally and mentally mocked and abused. Should this person just stay with their family, no other options? See if a friend won’t let them stay over for a few weeks until they get enough cash to get away? Should they just give up on everything, pretend to be a normal person and deal with their family’s abuse until the day comes they have enough money they can go somewhere, disappear and completely restart their life? This theoretical trans person’s body, mind, and now their living situation all seem like inescapable fucking prisons. They probably see no way out, and is probably very concerned that thoughts of suicide they dealt with before keep coming back. This trans person has tried to kill themselves before, multiple times. They can’t get rid of that horrible feeling in their body, just a constant dull ache of rage and shame bored like a hole in their gut that’s been there since they were a child. It makes them want to just act like a fucking animal, screaming and swinging fists. Makes them want to hurt themselves. Makes them want to hurt the people who just will never ‘get it’. Makes them want to hurt someone because maybe they’ll understand why after you make it crystal fucking clear to them, or maybe because it might help make the aching go away. This trans person doesn’t want to hurt anyone, for any reason. They just want someone to treat them like a person, and not like some useless fucking piece of garbage. They feel like their mind isn’t working right, or that they’re lying to themselves about reality. This theoretical trans person probably feels like they need outside help like it’s the only thing that can help them anymore, because god knows their brain is just fried and panicked and fucking spinning in circles at all times at this point. What should they do, in this kind of theoretical situation? Are they just fucked?
