11 years ago, I got Bad a levels (EED) and I genuinely thought that was it, I know exactly how you feel. I wanted to sit there feeling sorry for myself.
My family straight away made me get a job and have been working in retail since. Since then, I got married and have 2 children and also have a mortgage on my house. Up until a few years ago, I thought I'd never study again, I felt I was not smart enough, but recently I just felt confident enough to go back to studying and change career (I'm starting an access course and hoping to do Audiology).
It's ironic really, because I actually enjoy my work a lot more now than ten years ago. I think it's to do with life experience and gaining your confidence again (for me this was through my job) and having the right people around you (my wife, family and colleagues) and having different responsibilities (family) to when I was younger.
I know exactly how you feel, my advice is to not think it's the end of the world and whatever you do, enjoy yourself, work as hard as you can and learn from it.
And remember, life isn't simple, whatever path you take, as everyone has problems to deal with (or you could say, the grass isn't always greener on the other side :-)
