Obviously came to mind from another thread.
I don't have a specific year that was my worst, I've had loads that were terrible. I've also had loads that were amazing.
I'll go with 2019, incredible holiday in February to the Icehotel in Sweden, where my husband proposed, whirlwind 6 months of planning a wedding and an incredible wedding in August and holiday to the Lake district with our pups.
Next year may change that though as our baby is due in May!
