What are good home remedies that you can do to get rid of really bad acne?

Wrong approach: Acne is a chronic, non-lifestyle-related disease that's a grave personal and professional liability. Nothing you can do at home will clear severe acne. You need a physician's help. The medicines cost relatively little except for isotretinoin, but even if this is necessary, it's cheaper than not being able to get a job because of your face. Do what you need to.
