You are not the first person to flunk college, but it is understandable that you feel down. Perhaps you are not cut out for it yet. Perhaps you could get a job, learn as you say on the job, and come back to a degree later when you are ready and motivated. I was not ready to start on my degree until I was 29 and my sister held off into her forties, and then went onto do a masters! In the UK there is increasing scope for traineeships where people learn on the job as the cost of university education has soared. Some continental countries are more advanced in this respect I believe.
