BRAF mutation V600e?

I didn’t realize I was positive for the BRAF gene and had no idea what it was , until I went back and looked at my charts tonight after my TT. And reading everything online about poorer prognosis is super scary and has me literally bawling , as I have a 3 month old and am already struggling with all of this , and being positive for PTC classic subtype with clear margins but do have spread to lymph nodes . Does this mean shorter lifespan? What are other people’s experiences with the BRAF gene ? Thanks !
