If you can't afford your medications, look for drug patient assistance programs (PAPs). These are programs run by the drug companies to provide free or low cost meds to patients that can't afford them.

Are you short on time, broke, but want to eat healthy? Make overnight oats and homemade cup of noodles. Ramen noodles are great if you skip the seasoning packet (lots of sodium). Rice noodles are also cheap. Add some frozen veggies, spices of your choice, chicken broth (or use a bullion cube) and whatever else you'd like.
Are you in a city with ethnic supermarkets? They are typically cheaper than regular supermarkets, and it's full of new food ideas. These stores also have low cost dishes, pots and pans. The ones in my area have loads of cheap, fresh fruits and veggies as well as fresh fish. It's the best place to buy spices.
Check out your local Dollar store. You can find a lot of your home staples like toothpaste and soap. It doesn't seem like much, but I can get brand name toothpaste for $1 that would cost $3 at a regular store. FYI, Dollar General is more expensive than Dollar Tree.
Do you like gardening? Look into propagating plants. There are many plants that can be grown from a cutting or broken leaf. R/proplifting on Reddit can help. You don't need anything fancy. In most cases they can grow in a cup of water in a windowsill. When the roots develop, transfer them to a cup with soil. I've seen people selling these plants on Facebook Marketplace for $5 to $10 each. Wander around Home Depot's gardening section and see what materials you find. You can also propagate leeks, garlic, pineapples, green onions and more.
My local library has a tool library, free 3D printers, free access to the streaming service, Kanopy, free access to digital comic books, and interlibrary loan. If I find a book that I like, I'll read it first from the library, then purchase the books that I love.
If you have an EBT card (food stamps) see what you can use it with in your area. My area lets EBT users buy $1 admission to the zoo, the various museums, botanical gardens and more. My state also doubles the value of fresh fruits and veggies for EBT users and you can shop at local farmers markets. If you budget for $20 of produce, you'll end up with $40 worth.

Are there dental schools near you? They will typically offer free or very low cost dental work including cleanings.
