<p>"After a while though I entered a period of depression, not wanting to eat anything that resulted in my suffering from significant nourishment issues." - </p>
<p>Try something like:</p>
<p>"My grandfather's death left me dumbfounded; even after attending his wake, I couldn't fully comprehend that I would never see him again. I was detached, impartial, and unbelieving - unmoved at even the sight of his lifeless body, unwilling to accept that the clammy Thing in front of me had once been my grandfather. </p>
<p>Then, all at once, it hit me -- an emotional sucker-punch, straight to the gut. I never ate, slept, or ventured outside; at nine, I was already suffering from depression."</p>
<p>I mean, just off the top of my head. You could obviously improve it with some revision time.</p>
