"Who are you? You are the the truth out screaming these lies. You are the truth, saving my life."

So I'm so confused right now.
about everything.

it sounds lame but it's like, I don't know who I am.  What I want.  What I stand for.  I just live my life day to day, and I can't recognize what I'm living for.
I've changed so much.
At school I'm so different then when I'm with Alysha and Jessica (who go to a different school).  I'm afraid if people at school knew the real way i acted and the things I did they would be too surprised to understand.
If my family knew what I acted like, what I did they would be devastated.  They believe I'm so good. and I'm not.  I have so many flaws. I do so many things wrong.  They admire me so much and I don't know why.  If they knew the shit I've pulled, or what I do for fun, or that I have sex,  their pride would die.
I wake up every morning with so much pressure on my shoulders.. and I don't know how to handle it.
I know what I like. I know what I hate.  but it doesn't incorporate into what everybody else thinks I'm like.  It just doesn't work out.  if I was completely honest with who I was with everyone, my life would be a complete mess.
I'm confused.  I just don't know.

I really don't.
