Like MickeyCheeky said talk it over with the professional who are handling your care. They know you better than any of the rest of us and they are qualified to make an assessment. If their treatment is helping you the label is not so important. Mental health diagnosis can sometimes vary within a profession. One psychiatrist diagnosed me as schizoid then years later I have another 'label' from a different psychiatrist. Sheesh. There are also times when a person will have a number of issues that affect their mental health not just one.

I also struggle to retain information too and am in the habit of saying I understand when in reality it is like the other person is speaking in a foreign language that I don't understand. When I do need to remember I will write it down. That also saves on the embarrassment of re asking a question over and over.
Other times I will ask my T to send me an email with the key points in our sessions. I have recently taken to using my phone to take pictures of what I need. For example I took a picture of many books so I could get the authors names I did not have a pen and it was quicker.

I have also asked that my psychiatrist write down important things for me to remember down so there is a prompt for me.

I hope that you can clear things up with the professionals. Maybe there are other jobs that would suit you better in the future.
