I agree Pomona would be the best fit for you, but DO NOT live off campus with your mom.
You’re no longer a little kid. You can become autonomous and figure things out on campus - if you need accomodations, including someone to help you, ask the Office of Disability Services at each campus and see what they offer.
Most importantly, living in the dorms is crucial to “fitting in”, making friends, getting involved, etc. Research shows that students who live on campus actually are more involved, benefit more from their experience, and get better grades, than students who live off campus.
I understand that your mom could live nearby for reassurance and maybe because she wants to move along with you, but don’t live off campus. It’d be terribly lonely and difficult to handle.
How would you do with the study groups that take place at 10pm? You’d either miss them to be with your mom, r you’d leave your mom alone and would feel guilty.
Wouldn’t you want to live 5mn from the library, especially at exam time when you’ll be in there till midnight, one, or two (and wouldn’t it be a problem to wake your mom up at 2 am to get you from the library? Even if she claims it isn’t… come on… it is.)
