Here are some that made me tear up and or cry:

Angel in Blue (http://nicslash.livejournal.com/20082.html) by nicb0723
Summary: Officer Ackles is a hardened city cop who finds himself in the worst situation, staring down the barrel of a loaded gun. When Jared rescues the officer, Jensen owes Jared his life... or perhaps, it’s the other way around. An AU based on the movie, Angel Eyes.

Can You Help Me Remember How To Smile? (http://fatebegins.livejournal.com/56825.html) by fatebegins
Summary: Jared's been raising his sister's four year old twin boys, taking care of his Mama,his sister and trying to make ends meet at just 23 years of age. When he gets life changing news he has to make the decision to bring the boy to the father they never knew, a man he once loved with all his heart.

Life is Fragile (Handle With Care) (http://dontknowmyname.livejournal.com/63061.html) by dontknowmyname & blueeyedliz
Summary: High school student and resident rebel without a clue, Jensen Ackles, faces expulsion for a prank gone wrong. His punishment is eventually lessened to mandatory participation in the drama club's spring play. Forced to interact with the Pastor's son (and president of the geek squad) Jared Padalecki, the boys’ relationship blossoms from initial dislike into something much more unexpected. Until something terrible threatens to destroy everything they've worked so hard to create.

Thank you!!!! :)
