I'm a Scot too, so where's my vote?

Those of you who know me well will be under no illusions as to my heritage.
Despite having lived in Manchester for over 80% of my life, I still consider myself to be a native of my birthplace. I was born in Glasgow in the 70s. My immediate family is Scots. My extended family are all Scots and my ancestors hail from Fife and Shetland. I'll support Scotland over England in any sporting fixture that rears it's head. I may no longer have the accent, wear a kilt or know all the words to Auld Lang Syne but to the bottom of my heart I am a Scot.
But where's my vote? Because I simply live south of the border I am denied the opportunity to voice my opinion on what happens to the future of my homeland. Is that fair?
