First off, I want to commend you for realizing that SAD is something you need to take very seriously and incorporate into your planning for what happens in your future. I am happy to hear that you have appointments scheduled with health professionals and wish you the best as you deal with your health concerns.
I agree with others about your original college list.
There are two schools that I haven’t seen mentioned yet that meet many of the things you want. They are in liberal/progressive cities, but they are in conservative states. I will list the racial group that has the highest percentage of enrollment, and what that percentage is for the schools I mention below.
Trinity (TX): This school in San Antonio has about 2500 undergrads and is the first school that came to mind as I was reading what you want. It’s a strong school academically that is trying to attract more students from around the country, so if you can provide geographic diversity, that could benefit you. It is 54% white and 16% of students receive Pell grants.
Loyola New Orleans (LA): This is a Jesuit school (like BC) that has about 3300 undergrads. It’s about 45% white and 39% of students receive Pell grants.
Another school that was already mentioned that I want to second is Agnes Scott (GA). It’s a women’s college (that’s pretty open with respect to gender definitions, I believe) that has about 1k undergrads, 35% white, and 41% of students receive Pell grants. Nearly all the Atlanta schools participate in a consortium whereby students can take classes at other member schools (like Emory, Georgia Tech, SCAD, Spelman, Morehouse, etc.). You might also want to consider Spelman a women’s HBCU with about 3100 undergrads , 85% black, 42% receive Pell grants, and has a particularly strong relationship with the men’s college, Morehouse.
Between Texas, Louisiana, and Georgia, Georgia is probably the most liberal of the three states, but San Antonio, New Orleans, and Atlanta are definitely all blue dots on their state maps.
A school in a progressive state that I’m not sure has been mentioned yet is U. of Redlands in California. It has about 2300 undergrads, 42% Hispanic, and 33% of students receive a Pell grant.
