We are Muslim.
We're not celebrating on the basis of religion. More as a general festive feeling of togetherness, family and fun.
Growing up, we never celebrated Christmas. Our religious festivals are eid , we have two eids but since my parents both passed away,this is a time when me and my siblings feel the loss of our parents the most. All the childhood memories, all of the associations attached to it relate to our beloved parents , and they become the two most difficult and bittersweet days of the year.
My lovely mum finally breathed her last on my wedding anniversary day. My tenth, in fact. A week after my birthday, and a couple of weeks before the birth of my dc. The whole month passes by for me with memories of her , the pain she suffered through at the end, her last moments, her final words to me, the way she asked me about my unborn child before she left us forever. I can't celebrate my wedding anniversary anymore, my birthday and my dcs birthday are shadowed by that day in 2017 when the world lost the best mother that ever existed.
So I can't begin to describe the .... sense of relief , yes that's what it is, I feel, because this year I've 'done' Christmas and all I feel is happy and excited ! There are no prior associations for me ! There are - thankfully - no memories ! Just a delicious , clean slate that I can fill up with happiness and fun with me, my dh and my dc! Finally, it's something I can wholeheartedly embrace and enjoy without a single feeling of sadness and let me tell you, it's the best feeling ever ! 
I don't know why but I wanted to put my story out there and share it with you lot! You all probably think I'm bonkers but never mind
have a lovely Christmas everyone and an amazing time with your loved ones
