Have you tried contacting our one to one support service? http://www.breastcancercare.org.uk/breast-cancer-services/someone-talk/one-one-support
We've got a few volunteers who were diagnosed in their twenties. At the moment, none of them are based in Northern Ireland, but it might still help to chat on the phone.
To find out more or to be put in touch with a volunteer please contact our Peer Support Team on 0845 0771893 or by email at: firstname.lastname@example.org
