Anyways, start caring food with you like bread, grapes, collard leaves, etc. Something for her that she really likes. When she goes to nip at you stuff the food in her mouth instead.
My one young one was going through that for a little while, now I make sure I have treats of some sort on me. And now she comes to me when she wants something and I give her a handout.
Another thing too I have to be careful what color nail polish I wear when she is close cause she thinks my nails are berries if I wore red or purple. lol
You have made a major change in her life with not taking her to work everyday. That could have caused the boredom and aggression. Try taking her on some car rides, maybe some change will help her with her adjustment. They really Don't like when their routine is changed.
I hope this helps.
