Am I correct on both counts below in your opinion? 'I', he said, 'am frustrated.' The comma goes outside the introductory quote (I',) because the original sentence reads 'I am frustrated', not 'I, am frustrated'. But: 'I am frustrated,' he said, 'but I'll get over it.' The comma goes inside the introductory quote ('I am frustrated,') because it is needed to separate two independent clauses separated by a coordinating conjunction. The original sentence is 'I am frustrated, but I'll get over it.' Thank you.
