Not on the same scale at all... but I moved from Bedford up to Dundee when dad changed jobs, I was about 14yrs old and had lived in Bedford since I was about 4yrs old so was fairly grounded there with a big circle of friends, school and extra stuff at Rugby/Swimming clubs etc.
Yea, I missed my friends but I soon made other friends here and have kept in touch with the proper mates I had down there anyway.
Cheers,
Grant
