Try finding a local trainer that is also a behavioral specialist. Your vet may be able to refer you to one.
I was just reading Dr. Pitcairn's Guide to Natural Health today about emotional ties. He explains how our pets pick up on all the emotions in the family/household, so our negative emotions can have a not-so-good effect on their moods. On the other hand, it can also signal an underlying physical condition... either way I hope you're able to work it out
