Ok so feel ashamed, but then you still have to deal with this? You are maybe your worst critic, and being very harsh on yourself. Most other people really don't care that you failed, you are not unique in this respect? I wouldn't feel you have wasted your life, not at all. There are some issues here that perhaps you are not wanting to be realistic about? If in your heart you have given 300% and still not achieved your aims you have to ask if you are cut out for the course and the very job you are studying for? Most education facilities want you to succeed but there is a limit as to how much they can help someone. If you have genuinely struggled with the demands of just the study, how would you cope and deal with the rigours of the job demands? Maybe close one chapter and reassess? Look again at what it is you are so embarrassed about? There have to be failures in life, not everyone can win. How you deal with failure is very much more important than any success. If you keep shoulder barging a reinforced closed door it isn't going to open. Everything you have stated here suggests you are in that situation. So find the nearest opening to it, find a window and see what the view is out of that? Please go and find someone at the college or education unit to talk your options through. The hardest part of all of this is you accepting the situation you are in. One or two assignments can possibly be recovered from but a whole year?
