I Hate My Job So Much...*sigh*

I know this is going to sound like a lot of whining, but I need to get it out. I hate my job. I really do. It's not that I hate working, or even really the work I'm doing, I hate the atmosphere at work, the way the company treats us, and the way we're expected to treat the customers. It's not big things, not like, lawsuit worthy, but I really don't like it. The company is making all sorts of little demands that just make the job that much more stressful, when it's already really stressful to begin with. I work at a call center, for a mortgage company, and my responsibilities include taking calls and answering questions, and also taking payments. I wouldn't mind this too much if it wasn't so consistently hectic. We have less than 30 seconds between calls, and we're expected to thoroughly notate the account before moving on to the other call, so we end up putting people on hold, for which they chew us out if we leave them more than a few seconds. Plus, aside from our usual clocking in and out on our time cards, our time is monitored by the phone, so that we have to cut all our breaks short to make sure we can sign back into those on time. We were encouraged by our trainers to help one another, but we're not supposed to stand up, so that doesn't work too well. When we're not sure of something, our lead and our supervisor are supposed to be walking around helping us, but half the time the lead is supposed to be on the phone too, and our supervisor is always busy at her desk, so we end up keeping people waiting for ever while we wait to get help, since we're not supposed to get up and ask. They monitor all our calls and critique us on everything, and they try to encourage us to collect as much money as possible by getting us to compete for a prize at the end of the month for the highest collections. I hate asking people for money in general, and these people are usually cranky enough since it's money they don't have, especially with the way the market is looking right now. I'm also really not pleased with my supervisor. She's lying to us, pretty much, and making false promises. When we were first transferred to working for this company, she told me that she was considering me for the position of lead for the next training team. Turns out she promised that to three of us. And despite her promise, two of us aren't even eligible for the position anyway since we haven't been there six months, which she neglected to mention. And she keeps imposing all these little stupid mandatory rules, like having to take notes on every call with the notepad on the computer, even though some of us prefer using a pen and notepad instead. And the company keeps demanding us to work overtime because they're understaffed. I can't take much more of this, really I can't. I come home every night more mentally and physically exhausted than I've ever felt at any other job, and I wake up every day dreading work. It's not at all that I don't want to work, I want to be busy and I want to be managing my own finances instead of being dependent on my parents, but I don't want to be working a job that makes me feel this miserable. My dad thinks I'm copping out when I say stuff like this, that work isn't supposed to be easy. I'm not asking for it to be easy, but I'm gonna wind up with an ulcer if this continues. I'm looking as much as I can for another job, but in this small town there's not a lot to find. I just don't know what to do anymore. And I know I'm not the only one who feels this way either, a lot of my coworkers are complaining the same way. If it was just me I could see why my dad would say I was copping out, but almost all of us have our complaints. I know no matter what I do I won't get fired, because they need the people on the program, but I don't know how much longer I'll stay in this job, even if it means being unemployed again. all I want right now is to be back in school and working in something that really makes me happy.
