scatterbrained

If I'm not back in twenty minutes, pretend I was never here,
 like a game of hide-n-seek that never stops
I'm caught in between a rock and rest of my life.
Who'd have thought I'd be the one lost, I was so sure of everything.
Turns out I was wronger than Marilyn when she said diamonds are girls best friend.
Bright blue eyelash glue, not really worth anything.
Mine supported me through everything,
 but what I really need is some criticism and a waffle to brighten things up.
Like a rollercoaster sunset, up and down, can't decide whether it's setting or rising.
I'd grab on but it's hard with my rectangular fingertips.
I'm clumsy; it makes thing interesting but not any easier.
