Move anyway, if you can afford to get set up there, you'll find a filler job within a week of living there if you apply yourself, will meet new new social circle and can focus on getting a better one in the meantime.

I was having a psychology based conversation about something similar to this recently about behaviour and the conclusion was along the lines of the best way to change behaviour and self improve is to change your surroundings and situation.

Put simply your more likely to find a job you love in Manchester if your living in Manchester and seeing as that is clearly what you want you should move.
