Episiotomy stitches

So some of my stitches came undone maybe 4 days pp which left a gap/hole. I went to get it checked again at 2week pp and was told they don’t restitch and it will heal on its own!!

Anyone else experience this and healed fine?

Worried it will never heal back together because there’s nothing there holding it or forcing that, maybe I’ll just have a gap forever 😭😭

The place where it opened is the red, the piece of skin that holds both sides together at the bottom, green is the incision.
