I have been Skipping too much school, any advice on how to stop?

I am 15 years old and i'm in 10th grade. I have probably missed over 50 days of school. I know its a ridiculous amount. 1st semester of 10th grade i came probably once a week or so. I have been skipping since 7th grade when i moved to another state. The environment is so different from where i use to live and i pretty much never adapted to it. 1st semester of 10th grade was probably the worst i have been thus far. I have became afraid to interact with people,awkward, a lot of anxiety, depressed, and unmotivated. I am in a low point of my life and its hard to get back on my feet. In the beginning of second semester i made a comeback. i started out missing 1 day each week then i went everyday. I had all As, my parents were proud, i started to become more okay being around people and it felt good. The only reason i went everyday was because my father took me to school every morning, but now he cannot since he works far away.(my parents are divorced and my mom does not really help at all). I started to go downhill again. I went to school late then after a while i started missing days again and now i am back to where i was. I am very unmotivated and when people tell me i will fail and work at McDonalds it comes in one ear and out the other. You guys are probably going to say that i should just quit school and give up, but no i will not. There is something inside me that just will not give up. A spark that just need something to ignite it. I have had many come backs but i always fell back down. I feel as though the problem is the people and teachers, but what if i am the problem and i need to change things about myself. I have like no self control or discipline. I have a very unbalanced life. I spend all of my time on the computer. when i do not do homework or assignments i do not go to school for i can get an extra day to do it. Next thing you know. i never do it and i missed a bunch of days for no reason. I stay up late and then i am too sleepy for school. I wake up when school is over. Yeah i am a bum. I am chubby and self conscious about myself and i feel as though i cannot go to school if i look ugly. I do not know what to do or where to start. I have had a bad past and i really never got to be a kid. I need help badly. So guys any advice on what i should do to help myself and ensure a full recovery. A step by step would be much appreciated. If you need more information just tell me.
