If these panic attacks only occur when she is alone, it would appear that they are related to fears of being by herself–perhaps a fear of being hurt in some way, falling ill or even dying, and having no one around. If that’s the case, then providing her with emergency numbers and such resources might be of help. Also working out a plan to have various people check in on her from time to time might reassure her. Many times people who don’t like being alone benefit from having a radio or television on even though they are not really paying full attention to it because it brings the sound of human voices into the home and breaks the silence. It also distracts them from worrying about their fears.

There may be some other physical cause for her panic attacks, but that is something she would have to explore with her medical doctor.
