ELI5:Antibiotic Resistant Bacteria

I have heard a lot about antibiotic resistant bacteria and how dangerous it is. Can anyone explain how we got into this dangerous position and what this implies about the future of bacteria? How possible is a worldwide outbreak pandemonium based on this?

Basically what happened was that antibiotics were used so often, even for simple stuff such that the bacteria became resistant by natural selection. Once in a while, mutations may create a bacteria resistant to antibiotics. When antibiotics are used, all bacteria not resistant are killed off, leaving only resistant strains to reproduce and multiply, passing on their resistance. Thus, all the bacteria are now resistant to the antibiotics. Now we have to make new antibiotics to combat these bacteria.
