Maladaptive Daydreaming and Dissociation

I have just discovered the term "maladaptive daydreaming", and I feel overwhelmed. I cannot believe that I have never heard of it before, as this is something to which I totally relate. 

I first heard the term in relation to Dissociative Identity Disorder, which I don't have, although I do experience dissociation, and many aspects of DID overlap with my own mental health issues. I have now done a search on Google, and there are people discussing "Maladaptive Daydreaming Disorder" or "MDD", although it appears that this is probably not yet an official diagnostic category.
 

I have been trying to piece together my own jigsaw, due to the lack of interest and support from the mental health team, none of whom will even seriously discuss my depression with me, since changing my "primary diagnosis" to OCD. I know that they often resent my attempts to investigate my own mental health, and to learn about mental health disorders in general, but I only want some answers, and to find out what is going on with myself. 

I am also interested in finding out about different mental illnesses, so that I am in a better position to help and understand others. 

I am so fed-up with hearing that people shouldn't "self-diagnose", with either physical or mental health problems. I wouldn't even be diagnosed with dyspraxia had I not first "self-diagnosed", later having the diagnosis confirmed by professionals. Self-diagnosis can be dangerous, but so can just "going along with" what you know to be an inaccurate or incomplete diagnosis.

Anyway, I am going to research "maladaptive daydreaming" some more. I don't feel ready to explain it yet, as I am only just discovering about it myself, although believe me, it is nothing new that I am hearing about. The only aspect that has come as a shock to me is that there is actually a name for something which I have experienced since childhood.
