I self referred to the local mental health team and have had four telephone assessments now. The latest was today. They only concentrate on suicidal ideations. I told her I'd contacted them as I suspected bpd, she seemed surprised - despite me mentioning this in the previous assessments - then asked why I thought this. I told her about my symptoms (all of which are listed on the NHS website) and she said she didn't think I had bpd. She's referring me to the primary mental health team for short term support, probably counselling but they would look at my medication too, although unable to prescribe 
The reason I've had so many assessments was because I was told the team assessing would be able to offer long term support, so I feel let down. I know something isn't right. I've been taking antidepressants on and off for over 20 years but nothing improves. In truly to some of the crazy behaviour I mentioned she said she knows people who do that! I'm devastated that yet again I'm getting nowhere. I don't want to take up their precious resources for no reason, I just want some help, but it seems unless you kill yourself or are planning to kill someone else there is no help to be had 
I've no idea what to do now, where to turn. I've emailed them with everything I wanted to tell her, my symptoms, because I struggle with phone calls and get confused and forget things. I doubt it'll help though.
