Original post by therationalbeingWell, it appears you are rather distressed at your position in life, and so the immediate thing to tell you is that anxiety will not overcome the problem at hand.
First of all, you say you are predicted a D*D*D*, which is excellent. You should use the fact that your teachers believe in you so much, and that your work ethic, skill and input into the subject, is of such quality that you have been given such predicted grades; you should rejoice in that, since those grades clearly reflect your competence and ability in the subject. I believe that this on its own is motivation enough to tell you that you are clearly gifted in such an industry, and so you should continue to be such. We all have a place in society; some become doctors, lawyers, philosophers, economists, and guess what, we need engineers like you too (assuming you want to be an engineer of course). We need you, and more generally, the entire planet needs you, since you, along with everyone else working in unison, is integral to keeping our society alive, functioning and in harmony. Albeit, you are a small piece of that puzzle, but if you suddenly lose motivation now, fail your exams and do not become that engineer, you will always be that missing piece in our society that we can never find. Imagine a society without engineers; we would never have gotten to this age in our human development without them.
Indeed, remote teaching is different, but guess what; in the wild, it is the fittest that survive, and it is those that can adapt to their surroundings and thrive off that who become the top dogs. In fact, if you really think about it, remote learning allows you to make your own schedule, and really put in the work at home. Yes, you may have distractions, but you need to override your psychology by having that one goal in mind.
Actually, let me "reverse-engineer" the solution for you; in order for you to become an engineer, what do you need? Qualifications and experience. You will gain experience once you gain your qualifications, as your qualifications prove to employers, apprenticeship organisations and companies that you can display the work ethic, skill and effort to be productive and useful. Therefore, you are simply on the first step, which is to gain your qualifications. If you fail step one, you can never get to step two, in which you can never reach the ultimate goal. You are simply on the right path, albeit a difficult one, but you must adapt, and you must persevere in order to add some structure to your life, and re-discover why you truly took a BTEC in engineering in the first place.
To do good, you must overcome the self by submitting yourself to ritual. A ritual is not something you do over and over again, as you fall in the danger of becoming a habitual creature, which we do not want. Instead, a ritual is the process of breaking habits that ultimately allow you to become good, and in your context, gain qualifications. There is no such thing as a true, pre-given self, since this is always something you discover depending on your responses to external stimuli and your life experiences.
I hope this helped; remember, survive, evolve, learn, adapt.
