I've just had a panic attack and my emotions and anxiety are everywhere

Me and my ex broke up last May after 8 years together, I moved out at the end of that month with the kids, well he told me to leave. 2 months later he announced his 'new' relationship, later on I came to find out they were together before I moved out. 4 months later they were officially living together... Today I found out they are having a baby. All this has happened in the space of just 12 months, it's like every time I start getting my head straight and into a good space they drop another bombshell. I would never want him again because he used to abuse me in all ways imaginable but all this stuff happening is just building up and I don't know how to handle it.

*he's been blocked on all social media since last year, but because we live in such a small village everyone knows everybody's business and people talk so even though he's blocked I still find out stuff even unintentionally. I'd love to never have contact with him again but we have a child so it's hard and he lives right around the corner from my house.
