How do you spell German?

It really depends on what you are saying: If you are looking at a picture of yourself and saying "That is me!" then its Das bin ich. - That is I. (me) = ich

If your asking a question: "Do you love me?" "Liebst du mich?" - literally "Love you me?" - mich meaning "me"

Lastly Give it to me! - Gibt es zu mir! the Word "zu" makes the form of "me" change to "mir" there are other prepositions that do the same search "German prepositions" and ypu will get a list with all the different cases.
