You know what…. I think it is a bit of a tricky one and only you know what feels right
If you can afford to take time off and your boss is understanding, you could always try it??
Though this being said, if it were me I think I need to stay busy at work, by the sounds of it you are already at home on your own quite a bit… I would even think about just shortening your hours, maybe even an hour or an hour and a half less a day, enough time for you to get home, feed the pets and unwind……..
