I would definitely keep a job that doesn't feel ideal over being unemployed. Resume gaps are a real problem when looking our there and people will be paying attention! Do your best at work, but really focus on building out your escape plan lol. Put all your extra energy into resume building and putting out resumes. Don't ever think if it as coasting. You're planning for a better future one step at a time! Also, learning to put up with a job you're not thrilled about will come in great handy down the line (even if you land your dream job.)
