I'm sorry that you are going through this.

Since the issue seems to be money, is there an option for you to go to part time for college and increase work hours a little? Or not even increase hours. It sounds like you are really over extending yourself. Another option to avoid having to go days without food might be to supplement your food purchases with food banks.

Have you checked with any Mental Health Associations or Catholic Charities? Either agency may be able to help you find additional services. I know our MHA in our area helps MI individuals find housing as well as other support in the community.

Try to see if you can somehow work out 1 day a week where you can relax. Everyone needs down time.

Finally, is the AC yours? Or is the landlord responsible for it? I know when I had an apartment years ago in the Mohave desert in California the apartment was furnished with an AC. Not sure if that's the case in Florida?

Best of luck, I hope you find some relief.
