Vanishing twin?? Any hope??

Heather • Mommy of 💙💓💓💓💓👼👼

So I had my first scan yesterday only to find one of my babies is not going to make it.. One of my babies had a heart beat of 167 and measured 8+4 weeks. The other was an empty sac measuring 2.5 cm. My heart is broken, and I am so worried about the surviving twin. Have any of you gone through this ? What was the outcome ?
