I am in a situation where I can't exactly get help for my mental health issues. There are plenty, don't get me wrong, but there was one particular part of my mental health struggle that I could never...connect with anything else. I know I have trust issues and abandonment issues and so forth, but there was this one set of symptoms that kept bothering me. I like to have a name for something, even if it's not very specific, so I searched and searched to find something that fit me. Finally I stumbled upon DID, and the more research I did about the disorder the more sense everything made. Is it wrong that I did this? I just wanted answers, and I really wish that I could go to a doctor but I can't. I've heard both sides on self diagnosis and I want to see what a group of professionals would think. By the way, I haven't told anyone but my two closest friends, so no I'm not doing it for attention. I just wanted my symptoms to...make sense.
I think this is a borderline question. As a rule of thumb, we do not answer questions about individual health problems in favor of asking the author to see a professional, for both ethical and practical reasons. And let me be absolutely unequivocal here: you should see a professional. But this is fundamentally a general question about self-diagnosis, so I'm going to answer that.
It's always good to educate yourself. Accurate self diagnosis is necessarily impossible, however―what you can see depends on what you know, and what you know depends on what you have seen, etc. This is uncontroversial. Being educated is therefore very helpful when seeing a professional, which I again strongly encourage you to do, but it is never a substitute for seeing a professional when you have problems.
