Whats in a name you ask

What's in a name you ask, well a lot. I have been going by Diane my whole like until a few years ago I needed a passport,. I had to get my birth certificate and when it came my name was spelled Diana, now let me tell you the fun I have been having to change things over.. NOT.. I could have paid close to 300. to have one letter changed and then on top of that pay for  my passport. I chose to leave the A and starting going by Diana. The headache that has followed oh my..  Some things I can change and some I cant crazy
