I can relate. What worked for me was getting noise cancelling headphones and working inside a room with a door. It took some “training” (aka listening to loud music on noise cancelling headphones if she tried to interrupt) but she no longer interrupts me during work hours except on rare occasions when it actually is important. She will usually IM me too, instead of talking through the door. In other words, respect your own boundaries first. That goes a long way towards helping other people recognize the same boundaries.
