should i pursue a diagnosis?

my back story is here asperger-syndrome/topic56255.html
i got to see my psychologist and psychiatrist this past week, and brought up the possibility of AS (which i am pretty convinced i have). my psychologist said that i have "traits of AS;" my psychiatrist said i have mood-disorder and possibly (unspecified) ASD (i have also been diagnosed with depression, social/general anxiety, ocd, adhd). both dr.s, especially my psychologist, actually admitted a professional aversion to labeling, instead focusing on how to deal with problems etc. i understand and respect this aversion, to a point (well two points actually). (1)if said label would provide additional support, esp at work/school/etc >this is one reason i wanted an official diagnosis - i raised this concern and my psychiatrist said that both my adhd diagnosis and her professional opinion concerning ASD is enough to qualify for additional support in college (and at work, in the future). (2)after doiing extensive research I have concluded that i have AS. i fit the symptoms and such, but, more importantly, it explains a lot of things (about myself); the second reason i want(ed) an official diagnosis is to confirm this explanation. i really dont like the possibility that my own self-diagnosis is incorrect - i would feel like a fraud saying i have something if i dont, and the explanation would not even be real. however, although my doctors weren't as helpful in finding an official diagnosis (whether confirming or not), they did provide some affirmation: my psychologist was much more skeptical, probably felt like i was trying to mold my symptoms because i would always counter her objections-but i know that i wasnt trying to argue my way to a diagnosis, im just very scatterbrained and have difficulty saying everything unless i am prompted in some way (and i still wont even come close to saying everything); my psychiatrist actually said she wish i had told her some of the stuff i shared before now (most of it was info was trivial, not unusual to me, and only being shared with her because of various info about AS ive encountered) and eventually said the only AS trait i dont seem to have are "repetitive mannerisms" (to this i nearly laughed out loud - i probably did give off a chuckle or two - because i can never keep still: ive bitten my nails and crack my knuckles since i can remember, and am constantly chastised about both; i sucked my thumb well past the "normal" ago; i have trichtillomania, but i think its more the sensual feeling of hair that gets me; i cant sit still, the list goes on and on but ill stop now).
any way, im just wondering if (in your opinion) its worthwhile to try and get an "official" diagnosis (now or at some time in the future). it seems ill be able to get assistance i need in school (i dont really have tests any more, and everything i do is on a computer so im not even sure what assistance i would get at school). all thoughts, comments, etc are welcome/encouraged (whether directly or indirectly related).

Where you are from can have a bearing on whether you go for a dx or not. I don't think it is that easy to obtain in the UK (from what I have read) whereas the US seems to be more up to date with testing/referrals and so on.

However, I think the consequences of getting a dx are probably the same for both sets of countries: it can be a stigma (professionally) and as it is classed as a disability so you are supposed to reveal it each time you apply for a new position.

On a personal level, I completely understand why getting a dx can be so important. It provides those missing pieces to a puzzle.

AS is a psychiatric, not psychological, condition. so, don't expect much support from your psychologist. it isn't their world view. everything is 'software' to a psychologist, where as everything is hardware to a psychiatrist. the two world views are completely opposed and neither is absolutely correct. but you seem to be saying you have a diagnosis, just not in your opinion the 'right' diagnosis. under that circumstance, i can't see the harm in seeking to clarify your current diagnosis. and you clearly aren't happy with the status quo. so, unusually for me, i'd say go for it.
