I'm sorry if this should go in another part of the forum, or maybe in the advice thread and if so please move it there. I've posted this to several forums already and considering I need all the help and advise I can get, I'm going to post it here to. Is there any hope ?
Go to your local DMV or social security office and ask them. I'm sure they have procedures for this in place because I doubt you're the only one in this situation.
For your birth certificate it will be on file with the county you were born in, there should be a department of vital records, that has birth and death certificates. I didn't need an ID when I got a copy of my son's birth certificate, but that could vary by state or even by county.
