My life is spiraling downward,no way to tell if I'm going up or down,or even which is which.

I never know what I'm thinking yet I understand every word I speak,I'm always alone yet I have my self to talk to,I'm home schooled so I never know anybody but myself but my mom is here so shouldn't I know her?i know what I am but so far I've found that the person I know is only the person others know,so dose that mean I don't know me?I'm going crazy,that much I know,but dose that mean everyone else is sane?i know that everyone is crazy but others like me show that more then others,so should we all be locked away?the world I know is my computer and whats inside these four walls,i want out,but is there even a way to escape?
