How cute are you! It is normal to experience some separation anxiety when being away from your baby pup. You love him.
Just go back to the info in the movie that you turned me on to, "The Secret" and change your thoughts to only good positive thoughts when you are away. Envision yourself out having a grand time, no worries and then coming home when you are ready and that all is well for you and your pup.
Relax and enjoy and choose those positive thoughts!
