Sorry to hear this, I hope you all pull through and come out healthy on the other side of this.
I too have shifted some funds into DeFi, even though we are very much in need of more funds each day. I luckily have not withdrawn any of my DeFi earnings yet, and hope to keep those funds only for emergencies like the one you've found yourself in.
Are you able to easily convert your DeFi cryptos into cash without major fees?
