I'm going to go against everyone else and say "Get the Hell out of Dodge!" It's obvious you aren't happy. So why make yourself miserable just so you can say, "Well, I survived it...even though it was crummy!"? Life is too short to spend it doing something you're not happy doing. Yes, I know we've heard the whole when-life-hands-you-a-lemon cliche, but seriously, I only take that to heart about stuff I can't change. You CAN change this! If you've been there a while and still don't like it, just know you gave it a shot and you'd be happier elsewhere. So go!
And one more thing--everyone whines at some point. Some people more than others. But we don't know this girl, so how can we say she whines all the time? For all we know, she might be smiling her head off when she's not online.
