Hmmmm, here's my 2 cents! You mentioned social anxiety and sensory issues and 'other people' in your head. Have you been tested for Aspergers, or as they now call it: Autism Spectrum Disorder? I'm 53 years old...something has not been right with me since birth! I have horrible sensory sensitivity issues, major social anxiety (probably all the other anxieties, as well), nasty depression that won't go away, no matter what I take or how much of it I take. First I was dx'd with Major Depression, then Social Anxiety, then GAD, then ADD, was put on all kinds of meds (at 36 yrs old!!!! no one noticed, or cared about how much I was suffering, just that I was "selfish, dramatic, and a pain in their ass). It was the sensory sensitivities that got so bad that I started getting physically ill: ulcer, chronic fatigue, IBS. I started to go thru jobs like candy. Then I moved to The Town from Hell and just started to get fired and could not get re-hired anywhere else. So, after many visits to many doctors, I started a major research mission on my sensory issues...........and nothing matched all my symptoms as completely as Asperger's Syndrome. So, at 53 years old, I finally know I have Asperger's!!!! Can't tell from your avatar if you are male or female....my guess is female.....there is a huge difference between female Aspies and male Aspies. Also, it wasn't until 1994 (50 years after Asperger's was discovered) that females with Aspergers were discovered to exist. We existed all along, but no one noticed us. We cope differently, we were raised differently, and we show/present our symptoms differently......hence all the different dx's we are often given. There is an awesome test/quiz out there you can take online called The Aspie Quiz, I suggest taking it. It is long, but it is thorough and at least you can rule it out if your scores are very low. The quiz provides a very detailed "results summary" for you that you can print out for your p-doc. I scored a 177/200 in the Aspie traits and a 44/200 in the NeuroTypical traits. So "I'm very likely to be an Aspie".
It is the sensory issues which I've lived with all my life, that were never addressed or were swept under the rug, that made me wonder if there was something more going on. And also that I'm so treatment resistant to all the anti-depressants out there (tho' I've had some success with Lamictal, but in the lower dosages....I'm on 75 mg per day, split into 2 doses, am and pm). I've also discovered that lower doses work better.......I'm already hyper-sensitive to everything, stands to reason that medications and their doseages should be lower, as I'm probably going to be sensitive to those too. None of the SSRI's or the SNRI's (effexor, celexa) work for me, in fact they make everything 100 times worse!!!! Was on Effexor for 15 years, it did nothing!!! Then went on Prozac to get off the effexor due to the horrible withdrawls, Prozac made me extremely angry, all the time, so the p-doc put me on Paxil, now I'm paranoid and angry and still very depressed and anxious!! Going off that, tapering down slowly, as there are withdrawls to going off most SSRI's........ Tricyclics are out too!!!!
Most p-docs don't really know that much about females with Asperger's.....and they have way too many patients, so they just hand out the head candy and boot your butt out the door, so the next poor sap can get their meds, and so on..... I'd take the test...Google it and make sure you take the one called The Aspie Quiz!
Like I said.........at least you can rule it out, if nothing else. There's also a great book out there by Rudy Simone called "Aspergirls", it's a great read and really explains what it's like to be a girl with Aspergers. Aspergers is something you have for life, it is neurological, as opposed to psychological, you don't "grow out of it" and it is NOT just a "children's disorder" . Good luck and let us know how the test turns out!
