(Donnie POV)

I was in my lab wielding the Shellraiser so when we go patrolling later tonight it won't fall apart half way down the road and drawing down new weaponry and armor when I was thinking of what type of material I should use for the extra armor I heard someone..or something whisper "what's the point no one will appreciate anything you do " I looked around and i didn't see anyone I shook it off and continued drawing "quit running away from the truth" this voice whisper again I put down the note pad and shook my head, Donnie you need to get more sleep at night I said to myself I looked at the digital clock on my desk and gasped 12:00! Shit I'm an hour late for training!! I quickly grabbed my bō staff and ran out the door and I ran into the dojo, nice for you to join us Donatello! Splinter said mediating with my three other brothers sorry sensei, I said sitting down next to Leo it's okay my son just keep an eye on the time now mediate with us imagine your dream world, I do as I'm told I closed my eyes and imagine a world where there is no harm no shredder no villains no crimes and we can roam out at daytime and no one will scream or call us monsters they treat us like any other citizens and we don't have to hide anymore! "why are you thinking about a world like this it will never happen to you" I opened my eyes and looked around everyone is mediating I close my eyes again this time to something different it was dark the only thing there was April she had her back turned , why did you kill me Donnie I thought we were friends but I guess we aren't anymore are we! April turned her head to me her eyes are blood shot and her smile was wide and dark, black blood poured from her eyes and mouth then she melted into nothing then I hear Leo's voice you're weak and useless! then I hear Raph's it's an embarrassment to be your brother! Then Mikey's why do I look up to an idiot like you! Then splinter's you are a disappointment! These voices kept saying the same things over and over then vine like things grabbed me and one almost stabbed me but I gasped and I snapped out of meditation quickly "that's better" the voice said whoa what's up donnie you look..pale? Raph asked as everyone stared at me, Raph is right you look really pale Leo added I put I'm hand on my face, sorry guys..I don't feel too well I..I need to go lie down I got up and headed for the door, if you need anything tell me my son splinter said, hai sensei, as I walked out the door I feel a pain shoot through my head ah w-what the hell is going on?! I said holding my head I run to the bathroom turned on the sink and splashed water in my face as I dry my face with a towel I notice something strange my brown eyes turned to a crimson red maybe i'm just seeing things i took some medicine for the pounding headache I have and took a nap on the couch maybe I just need sleep.
