Mikey gets sick. So what happens when it turns for the worst?

It's been a few days now since the gang left Xaava-Dal and the Aeons. They had found and lost the first piece of the black-hole generator and are now hatching a plan to retrieve it from the Triceraton flagship. However, an argument, a rogue meteoroid and an unforeseen journey will interrupt the team's plans. Will they be able to save Mikey from himself? This is just an idea I had when I first saw the episode title back before it came out. This is my first fanfiction and I know everyone says this but please don't judge too harshly XD There will probably be a few mistakes as I go along but I hope you guys enjoy anyway :) Thanks! I do not own TMNT but I do own this story, so if you do repost anywhere, please give credit. Thanks :)

Mikey is the happy-go-lucky one. Always laughing, smiling, pranking...heck, he'd be awarded the most smiles award if there were one. When Mikey screws-up yet again, his brothers decide it is the last straw, and decide to give Mikey a dressing-down. And a very angry one at that. Everything goes downhill when Mikey decides to take his brother's harsh words to heart. Will they be able to save Mikey from himself as he changes for the worst? They sure hope so. Leo, Donnie and Raph venture into Mikey's mind, trying to save their brother before he becomes their worst nightmare. How will they unravel Mikey's secrets? Will they be able to help him in time before it is too late? Or will Mikey they knew and loved be lost to his dark side forever?
