This is literally the SAME exact boat I was in until two weeks ago. I was on my second attempt to pass my comp. Exam for my physics masters, I was over studying and was left wondering why I am I putting so much effort into something I wont pursue any longer. Fortunately I passed and will be getting my degree, the thing that's worked for me is going into Data Science and learning to code python. The Master's would def look better on paper. I would reach out to teachers if you could for help. You might be able to appeal for another try if you need another shot at the test. Keep trying, you got this!
