It sounds like you already know the answer, you're miserable, but it sounds like you need to push yourself to get out of there. I see people do it all the time, they're not happy, but it's "the easier way", but they're miserable at the same time.
You have choices, which ironically enough is the title of your post. Everyone has choices, I'm HAPPY I have choices today, because that means I get to choose to be happy or live in misery, and I will do whatever it takes to make me happy and save my sanity.
Hope that helps.
