Magz, I second all of Cheryl's advice and commentary. You need to know what you're dealing with and take charge of this pronto. I know that here in California there are programs for people without insurance, county hospitals and so forth. If you have no other resources try your county health department. I'm sure they can give you some suggestions.
I know it's tough to face a potentially bad situation. But you'll never know what it is until you get to a doc and get a biopsy. Take a deep breath, let it out slowly. If you're still feeling angry, turn that anger into proactivity. We're all here to support you. Please keep us informed, ok?
Courage.
