welcome, it makes sense to me. you said in the first post in this thread that you havent been diagnosed with depersonalization but have pushed the topic with your treatment provider because it does cause you problems...

if this was me the first step would be asking for diagnostic procedures for this.. once you get the diagnosis you can be treated for it...did you know that there are medicinal and non medicinal ways that can help to not dissociate to such extremes....it all depends upon what the triggers are that causes you to depersonalize.....

for example some of my triggers for depersonalization are depression/anxiety..I am on antidepressants that have drastically cut down on my having depersonalization symptoms.

Another example a trigger for me is my physical health issue of MS. but once I was on medication for that my MS related depersonalization symptoms went away.

another example I have bipolar disorder where I would have depersonalization symptoms. once I started treatment for bipolar disorder those depersonalization symptoms disappeared.

another example I have an eating disorder but once I entered a treatment center for that the depersonalization symptoms associated with my eating disorder went away.

sometimes stress from my job causes me to have depersonalization symptoms. when that happens I lighten my case load, take a few days vacation and those depersonalization symptoms go away.

sometimes I get depersonalization symptoms due to lack of sleep. when that happens I get myself back on a good sleep routine and those depersonalization symptoms disappear.

I also use ....grounding....to get myself back in touch with reality and that also lessens or fixes any of my depersonalization symptoms.

there are many different tools a person can use to combat depersonalization symptoms. but the first step to figuring out those tools is finding out where the depersonalization symptoms are coming from and why.

the best place to get information on your mental problems like possible as you call it split personality is through your treatment providers. like you have found out going on the internet can end up sending you to the wrong conclusions/wrong diagnosis/ wrong treatments that dont fit your exact problems... a lot of what you find on the internet about mental disorders depending upon your location is now outdated...

example here in the USA we have recently in the past year changed over to a new standard of what dissociative disorders are. someone goes online googling here in the USA they most likely will only find the outdated materials/information, some of which the treatments and tests are way out of use now with the mental health field here in the USA.

your profile says you are in Scotland not the USA so that may also be severely limiting what you are finding online unless you go to websites that are originating in Scotland.

my suggestion if you suspect you have dissociative disorders contact your treatment providers. they can help you get the diagnostic process for your location completed so that you will have the accurate diagnostics for you, rather then trying to self diagnose using the internet.

example did you know that in some fields of medicine, mental health, religions, cultures having those internal conversations and dissociative symptoms is considered to be normal, or can be any number of medical problems or any number of mental problems.

please let your treatment providers do the diagnosing. that way you wont end up doing more harm then good to yourself.
