Why Meharry? If you don't identify as with a historically underrepresented race/ethnicity, you won't fit there.
What feedback did you get with LSU? Is it just to retake the DAT? Would you do it if it saves you tens of thousands in debt?
You need to pay attention to in-state/out-of-state statistics. Texas schools are tough but not impossible with your GPA. But I'm not sure about other public schools like UAB, UMKC, Oklahoma (which I would check about), MUSC, or OHSU. I would have you consider many more private schools: Creighton, Marquette, LECOM, Case, BU, Tufts, Temple, both ATSU's. VCU also is OOS friendly as a state program. Perhaps Pitt. Again, your GPA/DAT combo should get some attention.
I am worried about your volunteering, which seems to be very tutoring heavy. What community service (in-person) have you done for at least 150 hours (not related to sorority, per se... it's better if you were off-campus now that you're in your gap/growth year)?/
