London is the love of my life. Our magnificent capital has been my happy home for 29 years. But every day my heart sinks a little lower, as I watch more flash developments slowly devour the city's vibrancy, diversity and soul. Billboards advertising "luxury flats coming soon" may as well read "your time is up, millennials!" The cost of living here is spiralling out of control, and the burden is becoming too much for the young to bear.
