Could I still get my diploma?

I'm 18. I turned 18 march 25 this year. I have 120 credits and I need 230 or 220. I passed freshmen year with C's and above but then I changed school with different lifestyle. Went from nice neighborhood to semi-ghetto. Different people and stuff. My stupid self decided to slack and not give a dam because i had a huge change with my mom leaving before becoming a sophmore. Failed my whole sophmore year. Went to homeschool and continuation school for junior to make it up. I really didnt like home school because it i felt lazier. I wanted to go back to regualr high school and try my best. I did. Senior year i felt normal but I judged for my low credits and they expected me to pass every single class with an A or B. I passed every senior class but I struggled in the soph. and jun. year because the teachers had really high expectations. I want to get my diploma so bad. I tried my best at the last high school I attented. But I dont know if they will accept me back or send me to adult school. I feel comfortable at high school. But if I dont go back then what are other options besides adult school or night school? Online? Perhaps?
