There is no profession with job security. Aviation is a bit less stable than the average, but I have seen friends lose their jobs in many different industries, not just aviation. The worse part is, they don't love what they do like I do.
I am coming out of a 6 month period of unemployment (my second in 3 years) and my new job is AMAZING compared to my previous. Hang in there! It is a stupid cliche, but that is all you can do.
