Is it worth making a GP appointment?

yeah my eyes might appear to be looking at the boob area sometimes when im not looking there lol 
not my fault they have awkward features in awkward places and leave me nowhere decent to rest my eyes.

Glad to have been of some help. Remember to take your test results in to the GP appointment. You might find looking at the autism diagnosis criteria and fitting your traits/experiences into the various sections. This is what I did, along with pages of notes on my various quirks, limitations and difficulties.

Hi. I’ve taken all of those tests, and the results have all indicated that I should be assessed as I am showing strong traits. My apprehension has come from my brothers experience, but this was years ago so hopefully I won’t have this issue. 

Thank you for this response - a lot of what you describe is very similar to how I feel/behave. 

My advice would be to take some online autism tests. AQ10 and AQ50 (sometimes called just 'AQ') are the most commonly used by clinicians in this country, but the RAADS-R is the most definitive. They can be found here: embrace-autism.com/.../
If you score in the autism range it will give you more certainty about following up on a diagnosis and some ammunition to convince your GP.

Not making eye contact is far from being a useful diagnostic criterion. It is not described as such in diagnostic guides, but an unusual presentation of eye contact is. Autistics can make too much eye contact, or too little, it can also be oddly timed eye contact. I'm a diagnosed autist and I make eye contact that is indistinguishable, to the observer, from that of neurotypicals, but I do it consciously. Conscious timing of eye contact is not neurotypical, they do it subconsciously.

I can also make small-talk, I don't particularly enjoy it, but I can do it. It tends to be rather rehearsed and stereotypical (weather related quite often). I find awkward silences far worse torture than making socially conventional, inconsequential, small-talk.

Do not be put off from seeking a diagnosis by finding that you do not fit certain stereotypes of autistic behaviour. Autism is a spectrum and it affects all autistics differently. I have never rocked or flapped my hands.

That's funny, it made me laugh. Just so long as you're not staring at their boobs, or moobs?? I generally end up looking at shoes! You can tell a lot about a person by their ****ing shoes, you know what I'm saying!

To be honest you sound like you are almost talking yourself out of it? Your points sound quite vague, generally when someone knows they are, they just know, end of, having examined all the traits involved etc. People can be socially awkward, or find certain things difficult, it doesn't necessarily mean they are autistic. Sure it's a spectrum, but there's usually a lot more to it than the things you mention. Maybe you could read up on it and try to figure out if you do feel it applies to you and take it from there.

Best case scenario, a GP will want strong indications of it to proceed.

yeah i usually use my peripheral vision, which can likely seem worse to them as usually i end up staring in other places, like a fat person it probably looks like im staring at their big belly.

Thank you, I’m apprehensive about it but I will request a different GP as we are registered to the same practice. 

I most certainly do not make eye contact, and even if it might look like I am, I'm not, my eyes are totally intentionally out of focus. Eyes make me want to throw up. If someone's too close it's like 'get the ***k out of my space'.

you should go ahead as the gp will say its a spectrum and you dont have to match every single tiny little trait as its a spectrum, you may have some and not other traits... but if the assessor was that strict with your brother on a single trait then i can see the issue and why it would put you off.

ive met plenty of diagnosed autists who can hold eye contact. theres one at work who only the other day was speaking to me while staring direct in my eyes.
