Once I found someone say in their conversation just like this
A: She is confused with her new lesson and B answered
B: Me too.
What I want to ask is whether "ME" is correct or not? or the answer must be I am too?
thanks for the answer.
But 'me too' is what is usually said in oral and informal English and is considered correct too. So it is perfectly acceptable in your example, but 'me too' should probably be avoided if you want to use very formal English.
