I used to love xmas as a child - we went to my grandparents and there were lots of cousins to play with.
Then later on with my ex's enormous family there were lots of different family catch-upset, meals etc to enjoy over the two week holiday.
I'm now a single mum with no new partner (and frankly not looking for one as life is complicated enough!). I've got an autistic child who struggles with too much noise and people. Over time this means I've been quite cut off from a lot of friends. I no longer have my ex's side of the family (abusive relationship). One of my parents is dead and they had a tiny family who we never see. My other parent is still alive and have lots of family but spread throughout the world. It just leaves me and my kids plus one parent who isn't really into xmas.
We do have special routines and nice food and time together but it's not the big family Christmas all my friends seems to have. Feels quite lonely, especially when my kids are away with their Dad. Really keen to heard from others in similar circumstances and how you make it special and/or come to terms with things not being what you hoped for.
