This is going to be a rough weekend for you, Jean17. Take your meds and exploit everything in your coping bag of tricks to make it through - odds are you will make it through your aunt's visit. As best you can, observe yourself during the weekend (my personal experience is that during a traumatic time observing oneself is exceptionally difficult). After the weekend's over, assess whatever observations you made. What worked? What didn't? What was more stressful? Less stressful? When is avoidance necessary? When can you safely confront stress?

Anyway, people will be here and ready to listen.
