At the end of the day you have to make the decision if you want to stay or leave, nobody else can make it for you chick.
But you sound miserable and that's one very good reason to leave.
On the other hand money might be a good reason to stay.
You have to weigh it up for yourself.
Have you tried easyjet at all? They have a base in GLA and EDI but even if you can't have one of those you can apply for wherever and put in for a transfer after 6 months probation.
Their training is thourough and can be hard but the trainers are supportive and nice.
And like everybody else said, there's plenty of other airlines if this one doesn't suit you...
Good luck.
