Try to have an ounce of patience. It goes a long way!

Remember that you're lucky to have a job that provides a salary you can live on, and that the work could always be demeaning or horrible or dirty or just plain unacceptable.

You've got an escape plan, so in the meantime keep working on that and don't get frustrated. You're doing what you can at the moment. You're not just accepting that this is all there is, and that's a good start. Keep applying and looking out for jobs, and I'm sure something will surely come calling for you!
