Sorry but your husband is in cloud cuckoo land.
What does he mean by 'proper' job?
Teaching can be a nightmare. My sisters are teachers and can't wait to leave. They are strong, fit 40 somethings and it has ground them down. With anxiety the children would eat you for breakfast.
You can't just walk in and be a doctor, lawyer, accountant or senior civil servant. You generally need qualifications which take time. Plus people start at the bottom and work up.
There are other roles that are 'starter' or 'trainee' that can lead to more 'professional' jobs such as a trainee paralegal or paraplanner. But competition is fierce and they aren't the quick fix to a high salary that your husband (not 'D' H) seems to want. It isn't going to happen and he needs to accept that. And without his pressure your anxiety might reduce.
You clearly enjoy teaching people. So I'm going to suggest the same as a PP.
Have a look at Teaching English as a Foreign Language or TEFL.
My uncle was a lorry driver for most of his life and started this when he retired. He absolutely loves it. He started with a couple of classes and is now nearly full time. You get the joys of teaching people who actually want to learn.
He obviously didn't have qualifications or experience to start off with but I don't think it took long.
It can be full or part time if you want and you might enjoy it - get some of your confidence back.
