lost my email address
I lost my email address and all my emails on my mac. I still can receive them on my iPhone. A message came up in iCloud saying if you do not save this you will lose it on your desk top. I thought I saved it. Guess not ugh! I am not computer savvy. Please help. I do have a time machine backup. However this did not seem to work. Thank you
