Never done this before

I have never done camping outside of a festival but I love the camping experience. I have no gear and no experience but I want to be in the middle of nowhere and just enjoy some time to myself. What do I need and where should I go as a first time wild camper? Money isn't necessarily a problem but I don't want to waste money if I don't have to. I don't drive so I know transport is a problem but I have friends that will drop me off in a spot and then pick me up. What should I buy and where should I go?
