Totally understand, I feel the same way, being "too different from what is considered to be DID" but on the other hand there's just so many symptoms that do fit the description.

Though there is the possibility that my psychosis is making the whole thing up.

Anyway, whichever way, there's hope.

If it's just psychosis, it will go away with time. If it's DID, then.. I'm just going to have to keep going to therapy, trying to make the most out of it, and eventually be diagnosed with DID and maybe even integrate.

I noticed you're in the UK, are the resources there as pitiful as in Finland? I know only three people in Finland who have been diagnosed with DID, and it's really not recommended to go suggesting to your therapist that you have DID around here (would probably send you to the loony ward right away hehe).. But I keep believing that once the diagnosis has been made, the proper treatment will be given.

Keep your head up high Kalamity Jane, things will get better and as time passes you will understand more about yourself.
