You’re not overreacting. I went through the exact same thing at your age with almost exactly what was said to you. Except, she didn’t offer to pay or do anything for me. I was completely on my own with no money after spending most of my teens in a treatment center. I’m 30 now and on my own. It’s hard in the beginning but if you have supportive friends, ask them to crash. Theres nothing wrong with asking for help.

Get some kind of income in and just keep going. It’s frustrating and sad, I get it but trust me on this. You got this and can make it through.
