Scarlett, use this experience as a stepping stone and take a leap now that you no longer enjoy it. Start applying for jobs now and see where it leads - If you are being paid under the going rate, there must be other jobs similar out there that have a more acceptable wage, and hopefully that you'll enjoy.
If you can't talk to your employers and feel that they don't value you, now is the time to move on - but try and get a new job before handing in your notice if money is tight.
Yes, some jobs are like this, but it doesn't mean you have to put up with it, nor should you. If things really aren't going to change for the better your answer is right there.
Good luck and all the best, Peas
