I think we should be less hard on ourselves with regarding mental health diagnosis, especially ADHD and Personality Disorders. ADHD is a " recent " phenomenon and is still a controversial topic including with more renowned and learned friends than my humble self. Please remember - and I speak from a position of experience - it is often " easier " for mental health professionals to fit service users into a diagnostic box. " Ah yes, Mr Smith, I've long thought he has depression. So as if I peruse my DSM 4 the treatment for depression is this and then .............". Diagnose - fit into box - follow the usual protocols for treatment.
My point is this, if we take Personality Disorders for example, of which there are 10 split into three categories, I meet some of the diagnostic " symptoms ". We all do. I can say without hesitation " I do that, I do that, I've behaved like that " have I got a personality disorder ? I simplify things to highlight my problem and of course there is a criteria one has to meet to get a PD but a note of caution. A mental health diagnosis can be very helpful, as it can clarify things for you, give you reassurence that your illness can be treated and give you hope for your recovery. It can give you peace of mind - which is the point right - but it can " follow " you around. It can lead to discriminatory practice against you, stigmatise you and clarify all the fears you have about being " mentally ill ".
Share your problems, speak to Professionals and loved ones about your feelings and experiences and seek knowledge wherever you can, but don't jump to conclusions, and don't set your mind on getting the same treatment everyone is different and one prescription does not fit all. We all have individual needs and we are unique. You deserve to be treat as an individual, and I hope you receive the support that is bespoke to you. This has been a lengthy post but I hope it makes sense, I hope you get treat as the very unique person you are.
