Kindness
Hi Romina,
I am really sorry to hear that the condititions of the job are harder than you expected. A lot of cc at legacy airlines also leave within the first year, because no one can prepare you for all the stuff that is part of the job, good and bad.
Can I if you can bear it hang in there a tiny bit longer for the experience, - it looks better on your resume (only if you can cope though - don't make yourself miserable - money is not that important).
Consider maybe doing a not too expensive correspondence or tafe, or even give your time to a charity for work experience etc course to get a few more skills so you can get work in other jobs, and other industries. A lot of employers will view your customer service experience highly.
But seriously, your happiness is way more important than anything, so get out now, before you get stuck, if it makes you feel bad going to work. A lot of cabin crew get stuck in a job they hate, making themselves and everyone around them miserable.
Some people stay as cc cause they think it is glamourous, but as you have found out there is not really any glamour, in a low cost or a legacy carrier. Its very hard work. Scrubbing toilets after people have done what they needed to, out of either end, yeah very glam!
