<human>: Can you give me a shortened version of the text?

Alright, I've never quite asked for advice before, and I'm not even sure if this is the right subreddit or not, but I just needed somewhere to go for this.

I'm currently a high school student who, if asked, would say that I'm not in high school. To explain this nonsensical statement, I'm basically failing all of my classes, and I feel like I cannot connect to anything in the school whatsoever (people, subjects, activities, etc.) I live with my mother (parents divorced, father in another state) who is slowly but surely turning to rage towards this lack of initiative in school, some of which I feel is justified, some of it not. 

Apart from this, I seem to have an extremely hard time focusing on certain subjects, mainly things that I cannot see an immediate use for. I love my job as a cashier and checker at a grocery store, for instance, but my mind seems to shut down when I'm sitting in that small desk, surrounded by other angsty teenagers, in geometry. I feel miserable about this when my mom feels the need to talk to me about my shortcomings, as I just feel worthless and helpless, never able to make my own decisions, never able to plan for my future, always stuck in this little realm of home, work, and school which-while seemingly stable- will soon be ripped apart by the harsh reality of adulthood.

Apart from this, I play video games. Way too much. There, got that one out. I feel that games that I play (Skyrim, Minecraft, TF2) have become a major escape from reality for me, and I will spend massive amounts of time playing, thinking, and contemplating them, instead of, you know, putting any thought into that history assignment that's due tomorrow, or the job that I may want to work at in the future.

I want to thank anyone who read all of this, and I'll be happy to answer questions related to my very splotchy and hurried-out wall of distressed gibberish.
<bot>: I'm a teenager who seems unable to focus on school or my future, and I worry that, come adulthood, I will have no skills, no job, and no ability to survive in the modern world.
