Hi Virginia,
I know loads of people who didn't like the job in the beginning.
I don't know what you did before but it's a lot of new things to get used to...the new environment, the long hours, working with different people every day, snotty pax (on the down side, obviously most pax are actually quite nice!), not learning one new job but a few (different roles), the whole aviation industry...
All of those people who didn't like it in the beginning love it now. It took them between 6 months and a year though.
If it's worth it? You have to decide for yourself if you want to give it that long. If you absolutly hate t, it's probably better to move on if you don't mind the bond payment. If you just don't like t because it's different from what you expected it's probably worth to give it some time. You say you like the pax bit and your colleagues....can't be that bad then, can it?
Sounds to me that you just need time getting used to it all...but please make up your own mind and follow your instincts :-)
