We were in a similar position last year (minus the cheating) we’d actually spent the week before Christmas in hospital and had no longer than 2 hours of sleep a day since she arrived. She was better out of the house as she had new distractions so it eased her crying a bit. It also meant there was lots of people to have her and to help, I even managed some sleep on Christmas Day! However that being said. I would never go anywhere with her at the time if I wasn’t up to it! You have to look after yourself first to be able to look after her. If you are struggling generally (not just with Christmas) going out then it may be worth giving your health visiting team for a bit of support but with Christmas do whatever feels right to you. I started going out to coffee shops and baby groups and would slowly start to extend the time each time probably around 4/5 months x
Ah so sorry you are going through this 😢 it's hard as it is without the added complications you are having. I wish your family was more supportive 😪 and NO, you are not in the wrong. Just listen to your heart and do what is best for you and your baby. If staying at home makes you feel better then communicate this to your closest people and make them realise you need their support and care right now. It's okay to ask and expect them to go out of their way given your circumstances. Best of luck and hope you have a peaceful Christmas 🎄 x
