I appreciate what you are saying. It's never nice to be told you failed, but this is generally how we grow as people, it's how you bounce back that makes you the person that you will become.
I left school with no qualifications at all. I then joined the Army as an infanteer and spent 13 years doing a job I loved and was good at. During that time I got military qualifications to do with radio use, medical, health & hygeine, water purification and a host of purely military qualifications. I also travelled around a lot and managed to get to see places on the planet that very few people will ever see apart from on nature programs or documentries.
I left for a couple of reasons, one was health the other was pride. I qualified as a computer engineer as pre-release. I couldn't get work with the normal "yeah you have the qual's, but you need the experience" excuses from potential employers. I then got a job as an opto-electronics test technician. Apart from my normal duties there I learnt about health and safety, PAT (portable appliance testing) and LEV (local exhaust and ventilation) amongst others. Within six months I had passed the senior techs exam and I was training engineers. My employers were going to send me on release to get my degree in Electronics lite. This however didn't work out for reasons detailed below.
After a year there was the opto - electronics crash and my employers cut the work force from just under 6,500 to 783, I retained my job. The factory was then sold to another firm for whom I worked for a further four years, the numbers of employees went up (2,500) and we were profitable, but not enough for those at the top, so they moved the whole set up to China and made all of us who had stuck with them through thick and thin redundant.
After a couple of years of trying like hell to get work in an area that had high levels of unemployment and a desperate work force I went self employed.
There is always another avenue to explore and keeping an open mind and by being adaptable you will be better able to handle life outside of halls of learning.
Good luck with it and as the others have said, chin up
