The end.
I'm really sad you never finished this. But oh well, that happens 90% of the time here at fanfiction dot net.
Still, I would love to know at least the general idea of what you had planned, because honestly this concept sounded dumb to me at first, but as I kept reading it got more and more interesting.

This is freaking creeping me out.

You see, a few years ago I was very depressed and I felt alone, so I made up an imaginary friend. He was really kind and friendly, and helped me with any decision I had to make, and with homework and stuff.

But then he started telling me bad things about the people who cared about me. He told me they didn't deserve me. That I was too good for them. He convinced me to get away from them. He told me what to say to them -very mean things- and I said them, word for word.

Then, when everybody was mad at me because I was an asshole, he started insulting ME. He told me that I was nothing. How easily I had been manipulated. He told me that HE was more ME than MYSELF. That HE was the one who should be in control. And he spoke so sure that he was gonna be able to do that. To literally replace me. I would become just an imaginary personality, while he would be the real person controlling my body.

Luckily, I'm still me. I was able to lock him away in my mind. For a while, he didn't completely go away so he still talked to me sometimes, insisting that he should be in control. But he wasn't. I ignored him, until he stopped talking completely.

I don't think this fanfic is gonna go like that at all, but it still reminded me of that dark time of my past.

Look before you leap!

"I mean, yeah, 'Dad's Driving Scares Me VII' was as gripping as it was utterly cliche trite seemingly made to capitalize on the fact that the move was in the morning"

(I think I spit out a bit of my tea laughing, goddammit author. Also, it sounds like this is probably what Fear[the best character indisputably] is thinking).

Being frightened of that move, I feel. Planes? It's cool, thousands of safety procedures and the company can't afford any sort of accident. I'll be taken care of.

Ships? Higher chance of bad shit, same responsibilities, and I just ain't afraid of deadly freezing water nor something silly like sharks actually being a threat to people. Feh, who cares?

Cars? Fuck that, every driver is fucking insane and I can't be in a car once without seeing someone doing something illegal in a way that can really screw a driver with less experience or a slower response time over. Lord help me and my nerves should the person I'm riding with get some road rage going.

"...except whenever Fear was cracking wise about it..."
(reminders of the great things about Fear as character. Also, so that last thing was him?)

thanks for the suitably weird dreams though, always bothered me that her dream sequences in the movie were too...normal. Even when I have dreams that real, it's either a memory or just one thing that's entirely normal. Like, a important location that is entirely true to life, but everything else is batshit crazy)

This is an awesome story-line, very intruding! I'd really enjoy another chapter, for you are very gifted in ideas, keep it up! :)

I suspects that if Riley stays in her current situation for a while, her hair is gonna start turning blue, and she's gonna start glowing...

aw man that was great, cant wait for the next chapter!

I don't think Joy is going to have a good life in the human world...

Oh dear...

Hmm. Well, they're useless without Joy.
Nice to finally have an update. . You're not the only one who's writing is going slow…it's like the holidays drained all inspiration.
This does mean that at the end (if there is an end .) either Riley will know about the emotions in her head, or she'll think it's all a dream.
What else can I say?
Interesting prose, as always, although the amount of abstract example (can't currently remember what it's really called) is sometimes confusing.

Wonder how the other emotions will react seeing Riley.

I'm kind of curious now as to what's up with Joy.

Wait for the meltdown in 3. 2. 1. and ...

Blastoff.

Dang.

But why is it so bad that she's holding Family Island's memory? I mean, they hold the core memories all the time right?

Either way, this is downright awesome, and I can't wait for more. {Wish for longer chaps though}

-Drunk

Well, that was short.

You seem to have inconsistent tense. Flipping between past tense and present tense. Try to keep it all past tense. This is a story, and you are the narrator. Don't describe things as if they're actually happening.

Cliffhanger end... O_O
