How difficult would it be for you to start over?

I have a family member who is going through some financial woes because they were swindled. She can’t sleep and worries all about what is going on. Her stress is through the roof.
I can empathize since it wasn’t so long ago that my husbands employers where losing a contract and he was told in a few months time everyone would be let go. Needless to say it was proving hard to find a job equivalent to what he was getting pay.
We had to finally settle for moving to find the better paying job.
Anyhow, he was stressed all the time. I told him not to worry and imagine the worst.
Worst being, bankruptcy and we may have to live with a family member till we were back on our feet.
We still would have our health, and both of us are able body and able to work any job if we had too.
It would mean starting over but we would still be able to have a roof over out head, food for our stomachs and he still had his retirement pay.
Our children are grown and self sufficient.
He said seeing it that way it didn’t seem so difficult.
I told the same to our relative and she also said it was true and seemed more relaxed afterwards.
So if you had to start over, do you think you can do it?
If you did, how did you manage through the stress?
