Just over a year ago I was having counselling and preparing to do a course I'd never considered at a poorly rated uni in the middle of nowhere.
Fast forward a year I've upgraded my course and moved to the one of the best unis in the country in Durham just because I got down to it and worked hard and achieved results.
It's possible to do what you want, you're actually in a decent position where you have little strings attached and you can start again and make what you want of your life, what are you interested in? Is there any profession you'd fancied working in but never took it further? Is there anywhere you'd wanted to live? Are there any jobs there?
You have to have the conviction and belief you can make a success of it but if you do believe in yourself you can make it happen, that's what makes people progress and make better of their life.
Never wonder what might have been, always think what can I make myself be, good luck.
