Google accounts driving me CRAZY!

There was a notice when I started using Picasa that I needed to update my blogger account to a google account. I started it before I got a gmail/google account. In the meantime I have set up a gmail account and all is fine and dandy except for the fact that they won't let me use my new gmail account as my primary email on my blogger account!!! If I want my gmail account to be my primary email on blogger I will have to create all new blogs!!!! It is so frustrating! If anyone knows of a way to fix this problem please let me know!!! I will love you forever!
