Deepest sympathies dear Sue. Hold on to faith and trust. Offer your SIL grace--he is grieving too and maybe wanting to protect your health due to lockdown as his kids are likely in lockdown too. Many changes for him I'm sure. We are all missing extended family just now due to the virus.

All will work out. You are loved by God. He will bring you peace. Keep hope and trust alive.

Feelings aren't facts. Jesus is with you. Focus on the good and the negative will lose its power. Seek professional therapy if you are depressed.

Please stop rehearsing the depressing thoughts. Cut them off. Worry will do you no good. Give it all to God to handle and then consider talking to a local pastor, counsellor and doctor and especially a credit counsellor. One step in front of the other and you will walk through this to joy.
