This is very profound for someone so young. I used to write like this when I was your age. First luv hunh. Take heart though young, there will be more. There will be plenty more.
As for the poem. Your flow is beautiful, there were a couple of ticks but the only thing I get from them is the thought that you just wrote this poem. You didn't think it out or plan it. You just wrote it.
I love it. It's the way I've felt lately almost to a tee. My bed's too big to sleep in and I can't stop my mind's running in circles. Well written poem and I'm really fond of it. Keep up the good work.
