My experiences of Christmas have been that it is really hard to make the first 'break' (in the chain of difficult Christmasses) and decide to spend it differently instead. I have been torn between wanting 'to make it work', hoping 'it won't be so bad this year', and being in a kind of knowing denial of needing 'not to lose the illusion of family'.
I had to do it gradually. I kept going back to my home town, but began spending part of Christmas Day with friends. Then almost the whole day. This year will be my first year where I have made that 'break'. But I had to really suffer last year to know that no matter how much I try to make it otherwise, it really is in my best interests to not put myself through it. For me it took that before I felt I could make a decision that is right for me. I'm spending Christmas with my partner, and I'm not visiting family at all until after New Year, where I will organise a 'get together' myself, with selected family members only. This year I will not end up in a helpless, suicidal, sobbing mess.
