Hey guys, I managed to get my hands on an Irish show called The Clinic
that Sheehan had a guest role in. Stumbled over it by accident really. I bought the series because Aiden Turner is in like a full seasons of it and then just by luck I noticed Sheehan pop up in an episode. Figured I'd upload it for those interested. It apparently aired late 2006 so Sheehan would have been about 18 (though he looks younger lol). Basically, he plays a diabetic kid who is scared of needles and has to be taught how to give himself insulin. And then it all goes horribly wrong from there.
EDIT: Here's a direct download link
for those who want it. Otherwise the full youtube vid is below.
