Who I am (V.2) Possible YWLJ?

So, this did very well when I first posted. Now, i think I've improved it a tad by adding bare punctuation. What do you think?

This is who I should be-
Flicking through magazines, seeing thin models
Cutting out the pictures, covering the mirror

This is who I want to be-
Staring at the pictures
Wanting to be more then just me.

This is who I am-
Turning in the mirror, trying to see every angle.
Grabbing the old toothbrush from the cup.

This is who I need to be-
As I lean over the toilet,
Retching filling the empty space.

This is who I’m stuck with-
As I flush the toilet,
Look into the sunken, gray face in the mirror
I was never happy with it.

Deep poem.
Grammar is in red.
Others are in blue.

* I get what you are going for, but is just seems a little incomplete without an indirect object pronoun. I confuddles me.

This is who I should be-
(I )flick through magazines, seeing thin models,?(confusing..it doesn't flow too well..)
Cutting out the pictures, covering the mirror.

This is who I want to be-
(I) stare at the pictures,
Wanting to be more then just me.

This is who I am-
(I) turn in the mirror, trying to see every angle.
Grabbing the old toothbrush from the cup.( fragment)

This is who I need to be-
I lean over the toilet,
Retching, filling the empty space.

This is who I’m stuck with-
I flush the toilet, -( here, it has a confusing switch of tense.It confuses the reader)
Looking into the sunken, gray face in the mirror
that I was never happy with. -By making that on sentence, it flows more, and takes away from the stapled-at-the-end feeling.

Overall, pretty good job. Just a few grammatical and structural errors.
But really good, nonetheless.

Hello there

This poem is utterly deep and I can totally relate to it. I don't think I've seen it before but it was quite good. What I don't get though is the statement

This is who I should be-
Flicking through magazines, seeing thin models
Cutting out the pictures, covering the mirror

You should be cutting pictures of thin models from the magazines? But you're not because you're too busy making yourself puke in the toilet. That's how I'm reading it right now, which is why I'm totally confused because I feel that's not your intention.
Great poem anyhow.
Keep writing and good luck!

~Happy New Year

Jojo got all the nitpicks, so this isn't going to be a review. Just saying nice job.
