The form "I" is always the subject of a verb. It may never be used as the object of a verb or a preposition. The form "me" is always the object of a verb or a preposition. It may never be the subject of a verb, except when the verb is in the infinitive in an object clause.
We say Do this for me, and Do this for my sister and me. ( NOT my sister and I!)

The one case where "me" may be the subject of a verb is when there is an infinitive verb in an object clause, for example " My sister saw me eat the apple," or "The teacher told me to stay after school."
