I'm gonna buck the trend here..
Aside from my sixth form & uni years (approx. 2004-2007ish) I'd actually say that I'm living my 'best' years now.
I've got a job that keeps me busy and pays decently, a boss girlfriend whom I'm living in a nice little apartment in the city centre with, I'm still very close to my family & some of my extended family, I'm travelling to new destinations more regularly than ever and my social life is very healthy. I still also (touch wood) have my health and everyone close to me still has theirs, which I'm very thankful for.
Literally the only negative in my life atm is Everton lol which I'm seriously reconsidering...
