Pretty normal for the first couple of years I would say. It’s partly just missing what was normal for Christmas, partly mourning the future you thought you would have. Christmas definitely feels strange after abuse. I was out a solid number of months before my first Christmas without him, and I knew I didn’t miss him, because I was well into processing the horrors, but he definitely intruded into my mind for the first few years. This is probably the first one where he hasn’t been at the forefront for me. I also get heightened anxiety around Christmas. Again, as a legacy of the abuse.
Hang on to the good bits. Reading a book is a lovely step forward. Mine this year was to go for a bath in the middle of Christmas day, because there was nothing I needed to do, and I felt like it! I can’t imagine having the courage to do that a few years ago!
