I know how you feel hun...

Could you go and speak to the careers' adviser at your old university? I know it has been a while, but they may be able to give you some guidance... Otherwise, I know it is very difficult to get a job at the moment, especially if you have been out of work for a while and even more so if you have a degree and the job doesn't require one, as they wonder why you would want to do it... It really annoys me, surely it is up to us to decide whether it is something we want to do?
Have you thought about volunteering? It may be easier to get a volunteer role, and then you may have the experience to apply for a job?
You will find something hun, don't dispair, but it may take time.
Best of luck!
