It seems like a good idea to give up flying and doing something else.
Think twice because most people who have done it wished they had not.
Being a flight attendant is a good job and there is absolutely nothing wrong in flying in your forties. The days have passed when pax expected only c/c in their 20's.
In the USA they fly into their 70's and 80's. One retired a few years ago aged 85 after 60 years in the air.
So it cannot be that bad.
I had to retire at 55 after 35 years with the same airline, I thought I was too young for the scrap heap at 55.
Getting another job now is difficult unless you are very young.
I know of a few who have gone into teacher training but have no idea what the others' have done.
I noticed a few like myself who had to retire youngish who now work on the ground for various airlines, it is hard to give up but after yo have left and miss the job it it is even harder to get back.
