ELI5: the difference between a psychologist and a psychiatrist

I have a feeling I know the difference on some levels, but I still get confused. Especially when I want to explain it to someone else, I can't find all the right words.

edit: thanks everyone for your insightful answers!

A psychiatrist is a medical doctor, who went to medical school and chose to specialize in psychiatry (just like how other medical students choose to specialize in being heart doctors or lung doctors).  A psychiatrist prescribes medicine and uses medicine to make you feel better. 
A psychologist does not use medicine. Instead psychologists use other methods for therapy such as counselling and making life and mentality alterations to make improve mental health. 

Some times psychiatrists don't think medicine is the fix for a patient so they refer them to a psychologist. 

Hope that helps.
