A graphic novel I read in 2011-2012

[heyitsrileyhereyep]

I Read a graphic novel a while back, I can't remember most of it but I remember it was a hell of a good book. The art style was cartoonish Kinda like the walking dead cartoonish. Not Charlie Brown cartoonish. All of the pages were detailed and coloured in. I'm pretty sure it was about this kid I think he may have had a sister and may have had blonde hair, he lived with his mom but it was a crappy place. Beer bottles and cans everywhere, his mom was really chubby and sat in a chair, pretty sure she had blonde hair too. She seemed to be an alcoholic but she died in that chair and the boy freaked out then the ambulance came. Then I think maybe he got into a secret service and worked under cover???? I also remember a scene he was in highschool and I think he punched a girl and then the brother of that girl got mad at him and said something like "my sister had to get 6 stitches cause of you".....I also think he wore an orange shirt. I know this isn't much info but I would love to read that book again. Please help.
