All done by ear. The strumming should come to you. 
Because like the first line E doesn't come after Am immediately. 
If you plan to strum each chord once you can strum Am twice before proceeding to 
E, also when switching from Dm to E but there is a pause before strumming the second Dm

       Am  E C E7              
Those eyes

It's not you, you wear up on your sleeve
             Dm                         E
The people stare as you walk down the street

I saw that by candlelight
                  Am   E C E7
From a brighter room
          Dm                              E
And the smile you wear on the outside deceives
             Dm                          E
The people stare as you walk down the street
      Dm                              E
