AR, you don't have to fly "AIRLINES" there are other forms of Aviation that are just as rewarding and as you say, you already have a Frozen ATPL. Perhaps you could look at Biz Jets, Survey flights, GA or other Aerial Work?
I actually got into the Airlines by default it wasn't my first choice that's for sure. I was quite happy doing Survey flying and other AW. Even got a commercial Seaplane Rating and that is also very rewarding flying.
Your Heart must really be in it. If you are in this game purely for money /life style, then unless you really fall on your feet then you are in for a great disappointment.
Good luck whatever you choice is.
