Vanishing Twin!

Sherry
Had my 6 week ultrasound BC I've had prior 2 prior miscarriages found 2 sacs 1 with a healthy heart beat & another that isn't developing.  The dr said it's a vanishing twin that my body will absorb.  Not sure how to feel about this part of me still feels a loss & the other part is happy that we have 1 so far w/ a healthy heartbeat.  Has anyone else dealt w this?
