I'm not diagnosed either, but do I need a geologist to tell me that a rock is a rock? I think not. Nobody knows me better than me....same with the "all of me's" (had to say that, lol!)
Actually....quite a few of the Others are still in disbelief or denial about all this because for some it doesn't feel real. For me....I'm the smart one and I can see it a mile coming.
Much of the angst left when I accepted what I feel is to be the truth. It's just a matter of stating the obvious. I knew since I was a mid-teen, but we hid it from society and ourselves. After a lifetime of miserable confusion....here we are at 49 being real....finally. It took us a year to come to grips with this all the while asking relating questions and studying about DID...till one day the pieces melded and everything made gut sense. So don't quit asking the hard questions....the answer lies within yourself....you just have to keep wading until it presents it's self as the truth. You will know it because you will repel from it like a hot iron to reconsider it or reject it. I guess for some, they need validation from a professional before acceptance.
Keep on writing regardless of your feelings....most of our Others hate sharing or typing (for that matter)...especially since we were accused of faking....(our crazy was too much I suppose)...but I'm not phased by it...too much. (We have a hard time relating to human kind as is)...which is why we come and go.
If you any questions....p.m. me or anyone here.
