Maybe time for a new clutch etc. Replace the motor mount and check the other side too, that side is hard to tell if its broke as the bracket underneath the rubber mount is hard to see. You might have to pry it with a large screwdriver to see if its OK . If they are broke, the motor will twist and also can move forward and backward, putting strain on drive train. Check to see that the line from the master is not bent or pinched going to the clutch.
