I agree with those that say “Get the heck out of there. “ Don’t give her the power to manipulate you. Don’t let her drive you to suicide. Don’t let her win. I agree that you need to talk to someone about your suicidal thoughts. I see that Colleen gave you some phone numbers.( I love that she always has resources for people to connect with. ) They are there for people like you that need help, advice and understanding. It does not make you weak to seek help, just the opposite. It takes strength and guts to fight back and stand up for yourself. Is there a reason you haven’t left. Did something happen when you turned 13? Your brother must be a bit older than you if he is an MD. Could you reach out to him for help. Maybe he could financially help you get out of your mother’s house. Maybe he doesn’t know what you are going through. You won’t know unless you reach out and share with him. Good luck! You can do this! You can win back your life!!
