Hello...!

I got a psychological evaluation about three weeks ago, and I was told that they would be finished with the results by the end of this week. There has been a bit of a concern internally for me... I feel as if I will receive an improper diagnosis. I feel like professionals will hesitate/not think to look into things that are a bit more rare, and therefore my symptoms may be overlooked and will be diagnosed as something where some of the same symptoms tend to easily overlap (like depression or anxiety).

I may be a bit of an annoying patient to have. I do my own research. *Obsessively*. If I think that something is wrong, I will analyze everything until I come to my own conclusions. I am open to professional ones, of course, and that's why I am getting a diagnosis - but I have a general idea of what the problem may be and have had an idea for quite a while. My symptoms generally seem to fit closely and overlap between schizoid personality disorder and schizotypal personality disorder (more so the second one). I am an adult (18), so I do "qualify" to be diagnosed with a PD. I just have a bit of a doubt that anyone would think about it when those two aren't very common at all - even if they are a professional who does testing and diagnoses for a living.

I may be going on a bit too long here, but... will my psychologist really be able to tell what my problem is with accuracy from a 2.5 hour cognitive test and then 30 minutes of true or false questions related to personality (which I may have answered inaccurately, since it was at the very end. I still remember some answers I should have marked differently)? My general symptoms were never really even addressed except for a little bit in the beginning... and I was a bit uncomfortable talking about them, since for some reason my mother had to be in the room with me.

If I feel that the diagnosis doesn't line up, would it be wise to converse and talk about it with my psychologist in order to settle on something that I agree actually matches? Is that even a thing you can do? I want any diagnosis to feel like a bit of a relief - like "ah, this feels like what's been happening to me for all those years! This is clear and makes perfect sense!" Instead of an "oh, some of the symptoms fit, I suppose, but it doesn't seem entirely right..." I don't want all my time and money and effort wasted with a diagnosis that doesn't even seem to be accurate. 

To anyone who has been through this process - do you have any advice on what I should do? I'm going to hope that my diagnosis is accurate, but I have my doubts.
