Please help. What are my chances at these colleges with a slightly lower GPA?

You will have no problem getting into any of those schools, and your GPA is very good. About the tuition I can't speak for everyone, but I personally choose the lower tuition school so that my family wouldn't have to struggle paying for it, and I regret it immensely because in doing that I gave up some of my dreams. But you have to weigh the pros and cons for yourself. About the anxiety I can relate because I have gone through times where it has affected me, but instead write about something you are pionate about because that will shine through better than an essay on your anxiety.
