Welcome to the insanity. I was just diagnosed in September but in reality I had a psychiatrist mention it 7 years ago. Four years ago I had another psychiatrist mention DBT but never put the referral in. I have no idea if he suspected BPD or not, he never said.

I think having the diagnosis was kind of a light bulb moment for me. It all started to make sense to me, how I act and feel. So for me the diagnosis has been helpful. I am not sure about England but in Canada without the diagnosis it is harder to get any sort of treatment that is covered by our medical system.
