How to make my horrible life better?

so im trying to better myself heres my life story sorry if its to long i just need to get this out. i am 20 lived in California all my life.when i was younger my dad was an alcoholic i would get home from school and he would be passed put on the floor he would always end up at the hospital and repeat all untill my freshmen year of high school.him and my mom would always fight and threaten to divorce but never did my whole elementary and middle school was like that.no one knows how greatly this affected me i became depressed in school didn't have many friends girls tried to approach me but i turned them down.in high school i made friends that ditched class and were up to no good.i ended up dropping out my senior year in highschool,now what? i am very lucky that i have two good friends from elementary school which are in college now and i dont see them much. i have cut off communication with my bad influence "friends" completely.so i now have no friends except the two in college.im actually a very good guy no drugs of any sort just very unlucky.anyways my dad no longer drinks and my parents are happy together. i am in adult school about to get my diploma. i want to go to college to become a doctor.so i can help people like the ones that helped my dad. do you think i can still make it? tell me your thought on my crazy life.
