Nostalgia

Nostaliga

Memory, recollection, nostaligia,
but it feels so fresh.
So much that tears threaten my eyes,
and I try to clear my mind.
So much raw emotion I felt,
that I feel I’ve lost.
That inspirational,
mental flair for drama
that I used to have.
It dulls the life I have now,
as if I’ve lost feeling,
become numb to love.

I wonder,
if this is what it’s like
to be grown up,
or if this is the aftermath
of my once broken heart.
The memories seem so distant,
but the scars have settled in.
I want my heart back whole.

and I try to clear my mind.

you may want to give us some better imagery, like similes or metaphors. Raw emotion is one of those "descriptions" that gives us no idea what you actually mean.
The part with, I feel I've lost/That inspirational flare, you have a period separating them, that leads me to think that you want them to be separate thoughts. But the structure says otherwise =p to make them one and the same so they faded into each other, but that period messes it up.

There wasn't must of a transition from the first stanza to the second one. >.> It kinda jumped and it serves little purpose =[.
The questions themselves, I do like, a lot. As for your ending, I would have choose the ironic statement of saying that You'd love to have your heart back whole, rather than wanting it. =p But that's just me.

Good luck, keep writing.
Silented1.

I would agree with silented1 - the word 'nostalgia' in itself if such a nostalgic word, and makes me feel the emotion without you having to say much else! Your phrases are quite literal, with mostly internal monologue, and little reflection outwardly. A poem full of raw emotion actually comes across as incomprehensible to the readers, for the simple reason that it sits within the writer, and is not accessible by the readers. Emotion is an internal thing. To get across your emotion to us, try to externalise it - this is where the metaphors or symbols come in. Tell us a story; be imaginative, play around with simple instances around you - give us some solid, concrete examples and it will bring the nostalgia to life!
