I need serious help email compromised and need to find ip address

Hi,

My gmail account was used to send me a fraud copy of my license last night.  But it was sent from my account.  I know I did not send it.  I want to find the ip address and I need to find it quick as a fake driver's license can be used to get me in a lot of trouble.  Can anyone out there help me?
