Hi OP
Sorry you were by yourself last year and also sad that your mixed race heritage is making you feel separate from your extended family and not wanting to be part of the Christmas get together.
Is this coming in any way from them, or is it only your feeling in your OP they can’t relate to your life experience that is making you feel distance? If there has been racism, I can totally understand you choosing not to be around them for your own well-being. If it the latter, lots of people feel different and their family, can’t relate to their life experiences, have nothing in common, but still spend Christmas together.
I don’t want to assume anything, but many grandparents in particular have a strong bond with their grandchildren. Your Nan might love the opportunity to be with you at Christmas, I don’t know how old she is, but would give anything to spend another day with mine 😥. If you focussed on being with her and making it a good day for her, might that make it more enjoyable for you, as it shifts attention off yourself?
Otherwise, what about your friends? Can you possibly join one of their Christmas gatherings? I would love to have my DC friend join us, even more so knowing they would otherwise be by themselves. Many of your friend’s parents may feel the same way as me?
Would you want to volunteer at a charity, that could be very rewarding to make a difference to others who are struggling for whatever reason and take your attention off yourself and being alone?
If you are going to spend it by yourself, what would be your perfect day? Could you start preparing for that, like save up treats, make a new play list, write a plan of how you will spend your day?
Hope some more people come on and post. Lots of love to you OP.
