Incidentally, "I am gone" is an old-fashioned way of saying "I have gone". Centuries ago, some verbs formed the present perfect with "to be" instead of "to have". This is still the case with French, German and some other languages: usually, verbs of motion take "to be" and other verbs take "to have".

Modern English uses only "to have" for the present perfect. But "I am gone" is still sometimes used in poetry, because it sounds a bit more poetic.
