Last summer I had a healthy garden but still needed to purchase some veggies. So instead of the supermarket, I bought what I needed at our local Farmer's Market. I was surprised to discover that not only was it cheaper, the vegetables lasted much longer than the store stuff.
The other wonderful thing I discovered was community. People of all different ethnic backgrounds, working hard to grow and sell healthy food and who would laugh and chat as the art of the barter was engaged. 
You sound pretty miserable. Perhaps connecting with some of the people you have disparaged would be good for you. And vegetables will help a whole lot with that bunged up issue you seem to be struggling with.
