It might be separation anxiety but to me it just sounds like she is bored. If your mom could walk her while you are away, it would relieve her boredom and help her relax more.
When my girl had separation anxiety, she barked, howled, and destroyed everything in sight.
My girl still paces even when I am home, if she doesn't get enough exercise and mental stimulation. I play with her plenty, but she also does better if we do at the very least, some basic OB stuff every day. They thrive on having a job and yours sounds like she needs one to feel content.
