Early on the OP stated she didn’t really want to go to school in Texas for several reasons, but a lot of responses are really focusing on Texas schools. I know there are valid reasons that people are pointing to Texas schools, and it should stay on the list, but primarily for safety (academic and financial) reasons, it should not be the focus.
Without knowing more about your school, (is it an academically challenging school, do a lot of students end up at top universities, etc) your stats seem very solid. Test scores would help if you are planning to submit them. I think the ECs look good, and how you tell the story of your ECs in your essays will help. You should definitely talk to your guidance counselor to see what input they have.
Without knowing more about your cost limits - and your EFC, its hard to say what sort of aid you would receive. From the larger school standpoint, you can always look at schools with auto-merit like U of Arizona, Mississippi State, U Alabama - there are others. Many schools have calculators or tables on their website that let you calculate what your merit award would be based on GPA and test scores.
