I've got to say, I've really very much enjoyed reading through this story, and I desperately hope there is more to come.
First of all, I truly adore the writing style (the whole stream of consciousness thing). I think it really works for this kind of story, where the emotional turmoil of the central character is a major focus. I really felt like I could understand Caleb, and I actually got a bit emotional over my own high school days while reading it. It's also great for character development, another area where you seem to succeed.
Actually, all your characters are really interesting. My favorites, besides Caleb, are Sara and Jake. With Sara, her emotional depth and sincerity despite her general demeanor really made her seem real, and just an all around cool chica. With Jake, it's more complicated. He's got some really serious problems, far worse than Caleb's (even if it wouldn't seem that way to Caleb), and even if they don't end up together, or if he hurts Caleb due to his own issues, I sincerely hope things work out for him and he can ground himself before his destructive actions and thoughts completely destroy him. He's on a fast track to serious problems, be it a deadly STD, the destruction of all of his positive relationships, or even emotional deterioration to the point of suicide. I truly hope he can get better, and I'd love to see Caleb help him, even though I doubt it'll happen considering Caleb's own emotional turbulence.
Also, I greatly dislike Ethan. He's quite the antagonist. lol.
Anyways, thank you so much for writing up to this point, and I really, REALLY hope another chapter is on its way. I know how hard it can be to finish a work once the inspiration starts to fade, but this work is honestly spectacular and it would be a waste not to ice the cake, so to speak. Hope you're doing well! Cheers!
