What can I do if the people I live with don’t allow me to wear undergarments and don’t let me get important things for myself?

Why are you dependent on these family members, and do you mean they are your family?

Forget the not being treated right. Just get out of there.

You said you get tuition, but they don't allow you to use the money. Whoever sends those checks will want to know where that money is going if you're not in school. That's a call you can make once you get away from there.

When you next go out in the day time, walk to the nearest police or fire station or neighbor farthest away .. someone who does not know you, and ask them to call the police to come to get you ~ don't give your name or address. At the police station, ask to speak in confidence, and explain you've been held as a prisoner in a home and you need help, a place to stay and to never return there ~ and that if you are returned to that place, those people will take revenge on you. Do not let anyone take you back, and do not ever go back. Good luck.

You are obviously not a senior if you are receiving tuition to live on.

You make some pretty gruesome accusations and then you shoot down every resource given to help you.

Sorry, I think that you need help and this is not the right place for your games.

Oh, you have very good grammar in your original question that went out the window in your responses because someone questioned your true abilities based on your grammar. So obvious!

You need to call APS and have them remove you from the premises, now. Tell them you fear for your life if they investigate and leave you there. They will find you a place to stay, food, etc.

Ok you’re real. Can you answer a few questions? How old are you? Who do you live with? Are you incontinent? Bedridden? Being computer literate & able to navigate your way here doesn’t mean you can actually take care of yourself. What is the reason you are in this situation?

Something tells me this could well be a scam. It’s a brand new poster, no Profile. The grammar is quite interesting – oddly accurate. The complaints are unlikely. Does OP want to find out how we’d respond to a poster, rather than to family members?

Good answer! Someone needs to look in on you.

It seems that you are quite computer literate. That's excellent.
Do google the Adult Protective Services in your area and tell them what you have told us. Ask them to pay you a visit in your home. Good luck.
