Hi have also been in the industry for 20 years. In the beginning i used to come home everyday and cry whilst i was on the course then i promised my sister that i would fly for the first summer. Which was a nightmare. I was your worlds worst nightmare!!
I then went on to fly for 20 years have been in 6 airlines ranging from commercial to charter to VIP and working for a royal family. I have abwsolutely loved it have made may freinds and aquaintances. (But unfortunately, didnt give up the career for anyone so subsequently have bocome too old to settle and have children) No fault but my own. But do you know what i still have that passion for flying. and would encourage any youngster to pursue a carrier in cabin crew.
Chin up and go and grab the world by the horns enjoy every moment of it and try and make someones day be it passengers or another crew member.
Have fun
and lots of luck
