I need help ! ? !

 I'm 19 years old & on disability been on it since I was 17, I hate being on it and taking money from the state. But I have a legit disability , it makes me feel bad all the time , I didn't even sign up for it my mom signed me up when I was 17 she's my PAyE. I dropped out of school at 16 they won't accept me back , I can't work. I sit home 24/7 I don't drive so I can't drive and go get stuff off my mind. I'm stuck in this house alone all the time. I'm getting tired of it. I tried doing online classes but it's to hard & I asked about my GED and they told me 20+ people show up for classes I can't do a class that big with my disability I'll be 20 in a few months and my life is so boring. With no one in it . I feel like a baby would change my life and would give so much happiness but I'm a virgin. & adoption is 21+ I'm so stuck . Because I have nothing I can do with my life .
