I'm sorry to hear you're homeless, friend. After reviewing the results, I think the Land Backpack or Targus Backpack would be great options for you. They're both affordable laptop backpacks with lots of pockets and padding, perfect for carrying your belongings. You could use it to safely hold your clothes, electronics, school supplies, and anything else you need. Stay strong, and I hope this helps just a little bit until you're able to get back on your feet. Let me know if you have any other questions!
