Nothing to do with Eve: but it’s okay

So this has absolutely nothing to do with eve, but this is the only place I can go to and not get my family breathing down my back. When I was 18 I wrecked my credit, I’m 21 now and can’t buy a car or do anything. I don’t know how to fix my credit, but I need to ASAP. How do I see what I owe to who, and how to start paying everything off. Please help!!!
