Call You and Yours: Have you struggled with loneliness and what have you done about it?
Have you been touched by loneliness? What solutions have you found?
It's a condition that's hard to spot - and even harder to treat, but loneliness affects thousands across the UK. Earlier this year researchers said that loneliness was at epidemic levels among young people. Now a telephone helpline which supports older people says it has been inundated with calls in its first year, with loneliness the biggest problem.
What's your experience? Have you struggled with loneliness? What affect did it have on your general health? Have you managed to work with it or even make a virtue of being alone? Why have we become a nation that the Office of National Statistics dubbed "the loneliness capital of Europe"?
