I got a diagnosis of BPD after seeing a psychiatrist three years ago. My GP didn’t tell me about the diagnosis and I didn’t know about it as the psychiatrist wrote to the GP directly and not me. My GP didn’t tell me about me having the diagnosis until I confronted him over a year after seeing a psychiatrist, as I felt something was not right and didn’t agree with him saying I just had ‘low mood’ and would improve with antidepressants. 
I was not recommended any support or advised what BPD even was by the GP and had to look it up all online myself. 
I have had face to face counselling for depression/anxiety as that was what my GP recommended. 
After 12 sessions of the counselling the counsellor agreed that the GP had let me down and advised that I get reassessed by a psychiatrist as they felt my BPD had worsened due to the lack of treatment and support to help me manage it. 
The GP that I had been seeing the whole time (over 3 years) had left the practise and I then had to speak to a new GP and explain everything to them from the beginning. 
Finally feel like I’m listened to and based of the counsellors recommendation has written to the psychiatrist to see if they will see me again. 
At the minute I’m on a possible 8 month waiting list to be seen again, my GP advised that I can’t go forward with any other counselling until I get reassessed as I’ve been advised that a lot of counsellor don’t or won’t treat BPD. So I need to wait to see what the psychiatrist thinks about my diagnosis. 
I have bought so many books to help with borderline and DBT but I just feel like I’m constantly being let down by the professionals.
