Chords/ Strumming Pattern Request for "I'm Ready" by Jack's Mannequin

Hey, new member and relatively new guitar player here. I've come across a few different sets of chords for this song posted online, and some seem to sound pretty close... but my real problem is figuring out the strumming pattern. If anyone could point me in the right direction, that would be greatly appreciated. The original song can be viewed at https://www.youtube.com/watch?v=Cx7LZxpUS50, and a good guitar cover can be found at https://www.youtube.com/watch?v=HSb3uzSG3dc. Thanks for reading!
