Kryptonite.

I took a walk around the world to ease my troubled mind. I left my body lying somewhere in the sands of time. I watched the world float to the dark side of the moon. I feel there is nothing I can do. After all I knew, it had to be something to do with you. I really don't mind what happens now and then, as long as you'll be my friend at the end. I'll keep you by my side with my superhuman might kryptonite. You called me strong, you called me weak, but still your secrets I will keep. You took for granted all the times, I never let you down. You stumbled in and bumped your head, if not for me then you'd be dead.  I picked you up and put you back on solid ground.
If I go crazy then will you still call me Superman?  
If I'm alive and well, will you be there, holding my hand?
