Moving to a new city

Hi I need some advise I want to move to a new city, as i feel where i live at the moment has become unsafe and over populated not only that I have been in the same job for 10 years and i feel there is just not much here for me to do to progress my career, its very small town. The problem is I am 27 and never really had to make new friends I know that sounds stupid but I have had same group of friends all my life. I'm very shy guy and don't give the best first impression because of that. moving away is something I have been thinking long and hard about and I'm excited about it but I just scared of how I'll fit in socially as I have never been put in the position where I need to make friends before and at my age scares me a little I would be more confident if I was 18/19 but 27 how does a 27 year old fit in.
