Options for a High School Dropout?

Ok so, here is the story. I'm from Chicago, IL. I went to HS until my sopre year. Pretty much was the 3rd one in my cl. I was in NHS. Unfortunately i decided to go to California because of school problems. I thought I would have more opportunities over there and stuff.. In California I went straight to Senior year since all the courses they required to be a senior I had them completed. On January 2010. My mom decided to bring me back to Chicago!!! =( So that messed up my whole life. I was 4 months away from Graduating. Once I got here when to my local school the one i used to go to.. And i was told i could not go back to that high school. I havent been attending hs ever since. And i do feel like a DROPOUT! Its making me crazy. it makes me think i'm a looser. I will never make it back to high school. I DONT KNOW WHAT TO DO!!!! What are my options? Any help will be appreciated!
