Hi
Well i did work as Cabin Crew till this week, i felt the same as you, i am 33 yrs old and this was my dream job since i was a toddler.
I started in March last year and as you can imagine i was on cloud 9.
In November time though i was just constantly tired, no social life, getting up at 02.30 hrs etc......
I just had to get out, i hated std-bys the most, not knowing if you were going to be called out, i felt like a prisoner in my own home, esp on std-bys where it was from 10.00 to 19.00 hrs, i was trapped all day,i had no control in my life.
I worked with fantastic people, a bit of an ok company it was a lo- cost airline, but i am much happier now i have left.
I always say follow your heart.
