Yes, it is also called Borderline but EUPD is a newer name and one that my psychiatrist uses.
I was diagnosed after a mental breakdown when I was hospitalised for 6 months. I have struggled with my mental health for as long as I can remember and have been in and out of therapy but this was my first hospitalisation. Initially I was diagnosed with reactive depression but after further assessment was given the diagnosis of EUPD.
In terms of how it manifests there are 9 symptoms - you do not need to have all to be diagnosed but I can relate to all 9. They are: fear of abandonment, unstable relationships, unclear or unstable self-image, impulsive, self-destructive behaviours, self harm, extreme emotional swings, chronic feelings of emptiness, intense anger, paranoia/dissociation.
One of the problems with EUPD is it can have a big affect on self-esteem which can make it difficult to feel 'worthy' enough to chat with other school mums especially to start the conversation. I am so grateful when someone talks to me and is kind at the school gate. The mood swings can mean some days I have really struggled to drag myself out of bed and know I look awful which makes it hard to interact. Another day I might be trying to hide self harm or anxiety might be going through the roof. Just a smile from someone else can mean the world. I might seem stand-offish at times but really I'm just trying to cope, I might not be able to talk but any kindness is so appreciated.
