Holiday season

Hi ladies, please forgive me with bringing a holiday season up but can I ask what your planning on doing for Christmas? I lost my newborn baby early this year and I honestly don’t want to celebrate at all, other than buying loads of decorations for his resting place and having a tree put up in memory of him, I don’t want to make plans for the day. My siblings all have their own children and I know it’s going to be hard feeling like the outsider without my little boy here to celebrate like the other children. I feel absolutely awful and so guilty for thinking this way but I just don’t want to be apart of Christmas this year. Does this make me a bad person? What should I do?
