I think you are being over-sensitive, OP.
Whether you like it or not, many people nowadays post details of their lives on social media... things that are a big deal, but also the day-to-day. It's how we live nowadays.
I love my DC to pieces but I remember the first time I felt comfortable leaving DC1 for a day out and the overwhelming sense of freedom/exhilaration. And the first time I had an entire weekend to myself, to sleep in, potter round, have a long bath, see friends, leave the house in under 10 minutes, stay out late and not have to worry about rushing back. Go to a restaurant and eat my food warm without having to feed someone else first.
It actually was a "big deal" to me. A huge deal. I hadn't realised until then how much of a toll being a parent to a young child and caring for them every day and every night had taken on my general wellbeing and sense of personhood. It was like looking in the mirror and temporarily finding someone I had lost - I remember thinking "Oh, there you are again."
I don't post my life on social media on a regular basis, but if I did I would have thought this would have been worthy of a mention. And I would have liked to think that most people would have understood.
