Seconds from killing me and our child

I decided to stand up for myself after my latest and last time of dealing with domestic violence with my sons father last month. I went to police this time. And I started telling about some of what i had been thru before this incident. The worst thing the person I loved did to me was almost 2 years ago. I was picked up by his hand around my neck and was strangled until i blacked out, while i was pregnant, And they have told me, that it takes seconds to die after blacking out. I am having such a hard time dealing with knowing me and my child were both so close to death by his fathers hands. Has anyone experienced this and how have you moved passed it? I regret being to scared to speak up when it happened, then i wouldn’t being going thru a custody battle, but it’s so scary and hard to explain how it feels knowing we almost died. How do I move on from this?
