I'm so sorry. travelsfar, I know that sick feeling from different life issues, it will pass but it's horrible while it's there. Others will be better placed than I to give advice but I hope it helps to be listened to and to know others feel for you. I don't know what I would do in your shoes other than try to be kind to myself, seek as much support as I could and leave the door open to my family. Maybe give it a couple of weeks and message or send a card to both your son and daughter in law, tell them you love them both and ask if a chat with them both together is possible. I'm not sure if you live alone or if you have a partner or husband, if so could they or another trusted family member perhaps mediate? Don't give up, it's very early days and change is possible.
