A proper diagnoses

I write this thread bc there are many people who come here from time to time, asking them if they have this or that disorder.

I have found along these years of therapy and psychiatrists and meds, that there are many possibilities that I am another BPD bad dignosed.
Like there are avoidants and many other disorders bad diagnosed.
I think the problem is that the psychiatrist bases the diagnoses in the visible symptons such as, depression, social anxiety, avoidance...some others, it seems to me that diagnose the symptons to avoid putting the patient a label.

It's needed a moré long-term knowledge. To study the past and the evolution of the individual from her/his childhood or at least, from the adolescence.
Many times, the patient lives events that (s)he thinks as normal so they are not told to the therapist. (This is my case).

It's not easy to do an accurate diagnoses. I'm not concern about it bc I need this of that label. I'm gonna be basically the same person. What it is very uselfull to know is the right therapy to follow.

Well, I only wanted to share this with you and I'd like to know what you think about the topic or your own experience.
