HELP! PIMPLE ISSUE!

Hello ladies! 
I'm having this serious problem with my face. Since I had my first period three years ago (regular) my face has been LOADED with pimples. My doctor has been giving me creams that aren't working so she referred me to a dermatologist. 
The dermatologist identified what kind of pimples I have and prescribed me a cream for my type of pimples. He said he wasn't sure if my insurance covered it but just to check at my pharmacy.
To my surprise the cream costs 847 dollars. 
Any suggestions on natural remedies I can use? Please give me advice because these pimples are just RUINING my self-esteem and I'm so self-conscious because I feel like people stare at my face rather than focus on me.
