How can I make my Christmas better?

I'm 18M and I have decided to spend Christmas alone, Christmas has never been good to me, I was born on the 29th December so it always feels like I have been shit on by the calendar, my family have never been bothered by Christmas so my childhood has been boring on Christmas, I was accidentally mugged at 17 Christmas dinner by someone I thought was a friend so I had to spend Christmas Day 17 with no phone, no cigarettes and in the cold, I spent last years Christmas self medicating and having a shit time, I have never had a Christmas like others and I don't really know what a good Christmas would feel like, I would like to this year try and make my Christmas experience better, what little things or big things can I do to make this years Christmas a better and more bearable time
