I'm a new poster here but I have been looking around now and then and reading other posts.

I was just wondering if anyone here was diagnosed with BPD (or EUPD as it is sometimes called here in the UK) under the age of 18. I'm currently 27 and have known about my diagnosis about 5 years though I have never agreed with it and have never had anyone explain the why's and where's that I fit into it. I feel I was only given it because of my long history of self-injury - now over 19 years. After some issues with my mental health team back in October / November (long story) I made an official complaint. I received a response to my complaint a few days ago and a previous psych who was interviewed as part of the investigation said that the diagnosis was actually given whilst I was under the child and adolescent mental health service (CAMHS) at 15 and he agreed with it when I was assessed by his team at 21. Neither me or my Mum were made aware of the diagnosis and I had no contact with mental health services from 16 until I was 21. So I was just wondering if it is usual for someone to be diagnosed with this so young? And if they thought I had it why would I then have no contact from any mental health professional until I asked for a referral at 21? Also, how can someone stick with a diagnosis made 6 years previously and not tell me about it?

I'm not sure what I am looking for here but I am a bit confused and was wondering if anyone might have some advice or comments to make.

Thanks.
