Right now you need to do what you need to do to get through this. If not going to the ranch today and visiting with people is stressing you out and making you feel anxious then don't go. You said yourself that you would rather take a morning nap with your daughter. I think that is what you should do if that is going to make you feel better. Remember you are number #1 and you have to start to take control of what you can control. You know what you need to do right now.
I know you had a busy and stressful time last week with visiting your mother and sister and I've read that you have been busy getting things ready for the yard sale. Maybe you need to listen to yourself more. It sounds like your body is telling you exactly what you need.
When was your last pdoc appt.? Do you see a therapist that could help you sort out your feelings along the way?
I hope you feel better today! (((Hugs)))
