I felt a like you created a main character I could be sympathetic to; however, I thought you told the reader how the main character felt alienated rather than showing it. I think that it would be more effective to describe what the character was doing so that the reader could see that he was alienated/ostracized rather than being told it so often. At one point the main character tells us that the lady that "adopted" him when she found him as a child was kind to him and that he felt he "owed her". Again, I think this would resonate more if you showed how this was so rather than just telling us. The dialogue such as "you've got this," for example felt very modern day young person to me. It just didn't seem like this type of dialogue matched the sort of world you were trying to describe. It was obvious that you put a lot of time and thought into this. I liked the flow of many of your sentences.
