I Really Need Help With A High Temperature Apartment

I desparately need advice for my apartment that regularly reaches over 80-90 degrees. Even when it was 30-40 degrees outside during the winter, Id be suffering the summer heat on the inside...

This is the layout of my apartment.

My living room and kitchen both have blackout blinds while the bedroom is the only window ever slightly cracked open, which has very light bed sheets covering them. Each have shutter blinds pulled to the top since my cat will wreck them if that factors into the situation in any way. I also typically leave the door to the bedroom open.

I have 1 box fan from walmart and 2 smaller sized circular honeywell fans that seem to do nothing in any way that Ive positioned them.
