Mine (so far!) was 2015. I had my first baby, happily married and everyone I loved was alive and doing well. We went on a couple of nice UK holidays with good weather. I spent my days seeing friends and getting to know my son and I was pretty healthy and just generally really really happy!
It all went a bit wrong in 2016 as my dad was diagnosed with a terminal illness and died shortly afterwards and I loved him to pieces. There have been happy years since and even this year, despite all the hardships in the world, has been a fairly happy one personally but in my mind nothing quite compares with 2015.
So what was your best year and why?
