hi. you know that she is under stress. i guess what she needs is time and you. give her some time. try to understand what can help her the most. think out her problem of changing jobs. if you can help her somehow to reduce her problems, don't hesitate! BUT you should help her gently. she shouldn't get angry at you.
then when she feels more relaxed, start again. now you should tell her that you understand but ask her for more time. you both need it. be patient and try to understand her a bit more (i know you understand her!).
