OP shared that she suffers from anxiety & depression, and that she is an avid snow skier. Has concerns about attending an all female school even though it is in a consortium & close to home.
OP: If taking one course at a time for 3.5 weeks will help alleviate your feelings of anxiety, then CC may be a good school for you since you like to ski.
Concerns about attending a single sex school may be a bit unwarranted since it is in a 5 school consortium with easy cross-registration privileges. Being close to home may also help when feeling anxious or depressed.
Since you shared that you are concerned about your mental health–including depression–the only advice that I can offer is to attend school close to home since your family is your support system.
P.S. OP: The key to which school is a better option for you may be in knowing what triggers your feelings of anxiety & depression.
