I screwed up, what can I do to turn my life around?

to be honest, your gpa is considered to be much higher than average, so youre beating yourself up for something you should be proud of. it sounds like you have some depression going on, which can be treated quite easily. i would definitely see a physician and see whether you just need some therapy or thearpy with meds- i suffered from depresion for years and kicked myself after i was put on zoloft for not doing it earlier. i used to let everything go and sabotage myself because i just didnt feel i deserved to succeed. about paying for school, there are ALWAYS options, esecially for someone with a pretty high gpa, from grants to scholarships to loans
