So many of you are contacting me and wanting in depth discussion about losing your co-multiple(s). While I have had some experience with this type of loss, I am not qualified to address the issue. Please contact Twinless Twins (www.twinlesstwins.org) in the United States and they will be able to help you. There are chapters all across the US and they have an annual meeting where survivors can sign up, attend, hear speakers, meet other twinless twins and gather resources.
I am so sorry for your loss(es). Twins, triplets and more come into the world together, research has shown that they are connected within the womb, but they usually do not leave the world at the same time. It can be a devastating situation for the survivor(s). You deserve proper support and connection and Twinless Twins is the place to find that support and connection. They can be reached at http://www.twinlesstwins.org
Very best wishes.
