The biggest factor in your future success is you not your school.
The schools that rejected you are in the rearview mirror. Reject them back.
Forget a gap year, you are ready for college now.
Accept positions on the waitlist. Write a short letter to Lehigh and Miami expressing your continued interest. Then visit and decide between Spelman and Temple. They are very different. Figure out which gives you more opportunity in the direction you want to go. Temple has a lot of really good students who go there because of money. You will find a niche of people like yourself.
I don’t think these choices are beneath you. You have to think positive.
