It might very well be the case that she senses a change in you since you came back. She may feel that you are being a bit aggressive somehow. MLC'ers are hypersensitive people and will get easily overwhelmed with even the slightest pressure/irritation from the LBS. I would advise that you practice utmost compassion in a completely non-pressuring way with her. I think you should say your bit expressing sympathy, ask if there is anything you can do for her, let her talk, ask if she needs help managing S5 and then completely back off. You can let her know you will be there for her IF she needs anything but stay out of her way.
Just from an observer's point of view, your PMA has been low since you returned for various justifiable reasons. She has perhaps sensed the same. Time to lie low for a while?

The 3 laws of DBing:
1. PMA is critical to DBing.
2. Since drop in WAW's PMA leads to drop in LBS's PMA and vice-versa detachment is critical.
3. Validate to raise WAW's PMA and GAL to raise LBS's.
