where can i find resources for autistic adults without cognitive disabilities?

i am 19 and while i am not cognitively disabled, i do struggle to do certain things independently such as making/keeping appointments, managing medications, leaving the house alone without being overwhelmed, and finding employment, among other things. i want my mother (and possibly also my best friend) to legally be able to help me but i do not want any of my rights taken away. i still want to have complete legal autonomy, just with my loved ones in a position to help me manage these things. most resources i see online are for parents/caregivers of autistic adults and not actually for us, so i figured id ask here. thank you!
