To be honest commander, i think what you are saying sounds just the same as any airlines training. i have only worked for 1 airline, but have a lot of friends at different airlines and all the training seems very similar...things are covered quickly and you are expected to take a lot in and then be tested on it, sometimes the same day, sometimes the next. You cannot possibly have a social life while undertaking this training. You have to eat, sleep and breathe cabin crew!
personally, i loved this!! i was willing to put in the extra time every spare second of every day, and believe me...if you think training is hard - wait till you're online with pre-flight briefings, and the thought that an emergency could occur at any second and YOU will have to deal with it. it doesn't necessarily get easier per say.
If you are so so miserable, there's no point staying. But as someone else mentioned, money issues could be a big enough reason for you personally to stick it out. Nobody can tell you what to do but we can advise, and i know that if i was feeling as stressed and upset as you seem to be. I wouldn't stay.
All the best chick!! welcome to aviation! (i think it's like marmite!! lol)
