I need health Insurance but I make enough money to get a good health insurance?

I don't want to get medi-cal because I don't want a handout I want to buy my own. I recently found lump inside my and only 20. I need insurance fast. Is there any good cheap insurance that I can afford monthly? I make about $300-$400 a month, I know it's not much I am trying to get a better job with no luck. So if anyone knows of good cheap insurance that I can buy i would be so appreciative. Thank you.
