I think you've probably hit the nail on the head with writing a much shorter email with less detail, but I can't agree with the conclusion you're drawing from that. I can't speak for the counsellors or referral services you've contacted so far. I'm not them and I don't know exactly what's happened when you've contacted them. So this is only my own impression and thoughts.
I wonder if you might be falling into black and white thinking - perceiving everyone to act the same way, or that you always get a particular type of response, even though there are variations. That strikes me about the quote from your blog, where you're talking about "society" refusing to acknowledge your situation. However, there are many individuals in society and if you look at the posts on myptsd.com alone, you'll see the potential within "society" for support for people who have been abused and victimised. We don't find it everywhere, but we can find it in places - amongst supporters, therapists, fellow sufferers and others.
In your first post you say
all my emails to counselors and referral services have been ignored
and then later you say:
In my experience many counsellors think they can treat a problem but when it comes down to it they don't have a clue about it
I'm not clear how you've experienced this if all emails to counsellors have been ignored.
At any rate, I think if you have a mindset that society won't help you and therapists will ignore you and/or misrepresent their capabilities, then you're unlikely to have a good experience of looking for help. Whether consciously or unconsciously, you're likely to be giving off signals that may be defensive, hostile, uncooperative, inconsistent or unrealistic. The people you interact with will inevitably pick up on those and might - consciously or unconsciously - shape their response to you accordingly. So it becomes a self-fulfilling prophecy.
For example, say I believe that wherever I work the people don't like me. With that belief I start a new job. Whenever someone is friendly towards me I'm suspicious of their motives. I know that people don't like me, so I think they're being fake or even manipulative. I'm guarded and quiet around them. They see and feel my reluctance to be friendly. They stop trying to chat to me. I notice that no-one chats to me but they all chat with each other. I decide I was right - people at work don't like me.
My suggestion for approaching potential therapists - if you still want to after seeing the person you have an appointment with - would be to write a little differently. I would
briefly state the symptoms I want help with, or the type of experience which is affecting me. By listing conditions, you seem to be self-diagnosing (with PTSD at least, you are stating that without a diagnosis). You may not be assessing this accurately, and you may be creating a barrier to getting support because of your own assumptions.
I would indicate that I wanted support and guidance for me to work through issues, rather than asking them to help me (which could give the impression that you want them to fix you). I would be relating the email to their type of approach and asking them questions rather than telling them things. I wouldn't go into much detail at all in a first email. I found psychotherapy through a different route, but I emailed somatic therapists when I was looking for one. As an example I just looked at what I said and it was along the lines of:
I'm interested in having craniosacral therapy. I saw from your website that you treat clients for trauma. I wondered if that included treating people who have experienced trauma as an adult, because this is my situation. I'm looking for a therapist who has trained and practised in this area. If you have, would it be possible for me to ring you to find out more about your approach and see whether we feel we could work together?
If you find the idea of an initial phone discussion too difficult, you could explain that and ask if it's possible to talk further by email.
For me, the next discussion is about me trying to find out about them. What training and experience do they have, what therapies do they practise, have they worked with clients who have experienced X, if so could they tell me a little about how they approached that, what do they do to keep things safe, how do they approach dissociation, etc etc.
The questions about safety, dissociation etc are to get past the statement of them being a trauma therapist and testing out what that actually means when they work with clients. If I used the time to tell them my history or diagnoses/self-diagnoses, then I wouldn't get enough sense of their skills, experience and approach to be able to judge whether it was worth having some trial sessions with them.
I'd suggest this sort of approach for the psychologist you have an appointment with. I hope that goes well but if not then I'd keep looking rather than settling simply because you got a response. Good luck.
