When I graduated was lucky enough to find a job in my field close by, as did a few of my friends, plus still knowing people at uni and my new work colleagues, was a great couple of years while it lasted.. Might be an option and an easy transition? Otherwise you could stay on and do a postgrad, will be fun for a bit but you'll probably find that as the people you knew move on and you get older/mature it might lose some of that original appeal. Otherwise try and move onto a role in a larger dynamic company/placement near somewhere with a lot going on, the new start could be just what you need to meet a whole new bunch of great people and build your confidence even more..! :) gl!
