My life back

I used to think that nothing's impossible, that nothing's unreachable but that thought
got lost. Somewhere down the line I changed and everything I once knew got erased.
I used to have no doubt in love and life and now I'm like a child who always wants to
hide. Afraid to open up and fly and time just passes me by. 
You're who I want, you're who I need, you're my only hope for survival, so just 
hold me, don't let go. I know you know me better than I ever will, so thank you for giving 
me unconditional love.
Still, I want my life back, when I was happy, when living had meaning and my heart was free.
No you can't be everything, even though you mean the world to me. You can't replace all
those things.
