Sue,
I'm happy that the assessment for carer assistance has been scheduled. Will keep my fingers crossed and say a prayer that she shows up and does not cancel after all this time trying to get the assessment scheduled.
For your electrical/computer issues, do you have a surge protector(s) to protect your computers. Not that they will make them totally full proof but any little bit helps versus running around unplugging everything in the house if there is a storm. Instead of being tied to the house for the care of a loved one or pet, you're tied to the house due to weather.
I can understand you wanting to be totally "free" during your respite time as you do deserve it. What if though there is a true emergency for which you are needed? Perhaps the agency itself could have your cell information in case there was an emergency and the carer called them.
