As a computer professional, I can tell you with 100% certainty that the prestige will make zero difference. CS is a ridiculously employable degree. And 99.99% of what you learn in computers will be on the job anyway. In about 3 years, employers won’t even ask where you went to school. Take a deep breath, apply for a school you can afford, and go there.
Also, uncertainty seems to be the new normal. If you can afford an expensive school now, that might not be true in 4 years. I recommend going somewhere in-state. If something happens, you could finish your degree with student loans.
