Invisible (Short story)

I alway knew that I was pratically invisible to everyone around me. I just never thought that I actually become invisible.
I never saw it coming, there was no forewarning. Well, it didn't happen instantly, it fazed in. It took around a month for the process to be complete is what I'm guessing, I don't actually know. I only noticed when it was in the final stages.
People have never really talked to me, family included. I was the youngest of three prodigies, but somehow I lucked out on anything special. My parents were so absorbed in the success of my siblings that past the age of eight they just stopped noticing they had a fourt child. I didn't particularily mind, I got to do whatever I wanted so it wasn't too bad.
At school I didn't ever have a friend. As hard as it is to believe I've never had one single friend, not even in kindergarden. I'm not sure why; okay I have a clue, it was most likely due to my extreme shyness which led to me not saying a word. I was fogotten, and I've just gotten used to it.
Getting back to the present.
If I think about it I did wake up from a usual nightmare a few weeks before my 'fading' occured. I can't remeber what is was about for the life of me, but I know it was terifying enough to wake me up in the middle of the night. Anyway, after that nightmare it seemed that eveyone started ignoring me more than before. Not even any passing glances in the hallway. Teachers kept forgetting to call me in the rollcall.
The finaly week of the process I noticed that I was actually fading away. My skin slowly became transparent until it was completely see though. The 'invisibleness' transferes to anything I touch, so it's not like there are floating clothes or anything. If possible my voice even became invisible because no matter how loud I shout, no one even takes note of it, they don't even look my way.
Sure I'm use to being ignored, but not at this level. I'm slowly forgetting what I look like and it feels like I'll just be blown away into dust by the wind. This is all I can do to try to retain some sort of sanity, but I don't even know id anyone will be able to read this. I hope so. I NEED to talk to someone. Anyone.
All I can hope for is that someone will notice me, or this 'invisbility' thing reverses, but somehow I doubt that will happen.
This will be the only evidence that I actually existed. That I was actually alive, and not some...some ghost.
Please read this and remeber me. Remember that I was alive. It's all I have left. Please dont' forget me. I don't want to be alone. I don't want to be ignored anymore.
