Womb Twins as possible reason for suicidal feelings

Dear All
I am posting this one-off message for you in the hope that it might strike a chord with someone and prove to be of some help. There is a lady called Althea Hayton in the UK who has researched for many years into a phenomenon she calls ‘Womb Twins’ (also known as Twinless Twins). These are people who had either a twin or multiple who died in the womb or at birth. The death of a twin, even at an early stage of development (several weeks into the pregnancy) has been linked to profound feelings of despair and wanting to die even though the person may not realise that they had a twin. This was the case for me. The website is wombtwin.com and contains a great deal of info including a psychological profile of womb twin survivors as Althea Hayton calls them. I am not sure if any of this applies to anyone posting their story on this site, but perhaps it might be of help.
Yours, Christina, a mum in the UK
