The pronoun 'I' works as a subject. It names who carries out an action or who is described by the verb, whether alone or with someone else. The pronoun 'me' works as an object. It names who receives an action, who receives an item, or who follows a preposition such as 'for' or 'with'. When you link John to yourself with 'and', the pair functions as a single grammatical unit in the sentence.

John and I are carrying the heavy boxes up the stairs.
