I know this thread is focused on financial-aid/scholarships, but have you looked at other career options apart from “Psychology with a minor in Social Work” (Mental Health Counselor)? Your SAT scores are good and you score 700 on the math section is impressive. You could do a Nursing degree (BSN) and then a Psychiatric-Mental Health Nurse Practitioner (PMHNP - MSN) degree. Psych-NPs make a lot more than mental health counselors, much higher demand and more autonomy/scope of practice.

I think you should look at FAMU. They have a BSN program (2+2) and also a PharmD program (another good alternative to Psychology/Social Work) . How did you do on your science courses in high school? Any AP courses?

Is your brother older than you? Interesting that you are both starting College at the same time. I think you should make another attempt at the SAT, preferably with a good commercially-available review course. Shoot for a CR+M of >=1400! Did you take the ACT?
I also like the suggestion @MYOS1634 made about other colleges that you should be looking at.
