@Molly71 thinking of you.
You and the other ladies have explained it perfectly. I also had a emotional crash after active treatment finished. I look back and reflect i was in the zone of shock then getting through treatment pushing forward and then I had crashed and had to heal myself. It does take time.
I try to do the things I enjoy now. Craft, baking, and taking down time for myself, watching a DVD or movie. My house isn't as pristine as it once used to be but I let myself do the things I want to do now. I don't let housework control my day. I do what I can.
