SingToTheSky - They just carried on with the discussion and everyone chipped in with their thoughts, right at the end they offered tea/biscuits for anyone who wanted it and everyone just stood around chatting to each other. I stood for 10 minutes looking at my watch every 30 seconds or so before the head researcher came over and asked if I needed to go, I managed to say yes and she said I was very quiet and was everything okay. I wanted to scream at her where was that an hour or 2 ago and quiet?! my entire contribution over the 2 hours was "I'm just a mum"..instead I just said I was fine and had to go. The wave of relief when I got outside of the building was intense and I cried for a solid 15 minutes in the car before I could tell DH what happened.
Hopefully, the coordinator has some decent knowledge of autism and won't assume you have no empathy, it's sad how certain stereotypes about autism exist. It is very true that when you've met one person with autism, you've met one person with autism. My DD and I are very different, for example, I have no friends or social skills but she has quite a few friends and has developed her social skills enough to come across as fairly NT (she's a very good masker whereas I can't do it very well).
I'm okay on the phone as long as it's someone calling me, even with my own family, it's always my mum or dad who call me I never call them. When I need to make a call (for an appointment for example) I have to really psych myself up and have some things written down to keep me on track with what I need to say/achieve from the call.
I looked into the OU again as they had an offer on where you could study an access course for free with them. I wasn't eligible because I'd previously studied with the OU yet I didn't get any kind of qualification they were 10 credit modules, so I have 30 credits in total and no actual qualification. I'm not sure if the same kind of funding available at an actual uni is available for studying with the OU, I'll have to look into it!
I hope you've managed to get some food! I struggle with that as well, I'm very lucky in that I have DH to remind me of things or I probably wouldn't shower/eat/go to bed at an appropriate time, etc.
BertieBotts - The only way I can describe it is like being trapped in your own mind, using the example of the research place, I was aware of what was being said by others and had lots I could have contributed but I just could not speak. I don't know how to explain other than my mouth just wouldn't open and make words despite my brain shouting the words at me and to just say it (if that makes sense). It's nowhere near as bad as when I was a child, at primary school I didn't speak at all, I can remember one incident where my year 4 teacher was so angry because I wouldn't speak, she screamed in my face asking what was wrong with me and why I wouldn't just say something, that they knew I could speak so why wouldn't I. Even now I have to go over and over something in my brain before I can bring it up with others verbally and it's 50/50 whether I actually say something.
I think emailing the tutor after might be a good solution, that's sort of worked in the past for things. When DD was at pre-school I joined the committee, during meetings I just couldn't say anything, I would just sit and nod along, then afterward send a whole load of suggestions/ideas via email.
