How can we diagnose personality disorders?

Hello doctor,

I feel like I have some sort of personality disorder. I can not quite pinpoint which one could it be. I looked into different types and thought I had found the one, but after a few weeks or months, my perception would change, and I would think I had a completely different disorder. So self-diagnosis seems impossible here. But I do not have anything to complain about. I am satisfied with my behavior. I am curious. Is it possible to test for every personality disorder out there? For one month, I was obsessed over how attention-seeking I was, so I believed I had HPD (Histrionic personality disorder). Now, after some time, I realize that I do not completely qualify under the diagnostic rules, but the attention-seeking behavior is still there. I was diagnosed after my suicide attempt with "personality disorder unspecified" and got told that I have BPD (Borderline personality disorder), but I do not believe it. I do not have mood instability. And my latest psychotherapist (I have got dropped by four therapists) said I was toying with this diagnosis. So, to conclude, I want to be 100 % sure that I do or do not have a personality disorder, and if I do not, then I want to know whether I am disordered in any formal way, or just I am that eccentric. I have also had a suicide attempt, but it was done purely out of curiosity and a desire to experience the process. I did not intend to die, and I knew I would not die. I was quite depressed at the moment, but my intentions were only to be flashy about this fact and not hurt myself in the long run.

I have been obsessed with suicide and self-harm since I was 15, so one of the goals on my bucket list for life was to attempt it. Previously, I have had a depressive episode for roughly a year (possibly the following burnout at school). Then at one point, I just switched, so I am not depressed anymore. Maybe the medication worked. Currently, I am taking Fluoxetine, Bupropion, and Chlorprothixene. I am currently attending a psychiatrist, but we only treat whatever is concerning me at the moment. I have not had any formal testing besides telling my situation after the suicide attempt. In the past, I have taken Sertraline, Quetiapine, Aripiprazole, Vortioxetine, Lamotrigine, and Flupentixol.
