You can try to deny your autism and low iq but acceptance is the first step of improvement, i believe in you accepting it and improve your psyche and get a job to not be a hurdle for society.

But keep the low iq music to you, nobody wants to listen to it, I know you try to get attention since you probably had no parents that think anything of you or actually anyone, but there is always a way out. I thought american schools teach too how to behave like a human, in case you missed it, it is recommendable.
