Hi English,
I found that, throughout my life, I have known my mum's needs almost before she did. I can tell you, with almost 100% accuracy, what she will say or do in any given situation, and what her thoughts on that situation would be. This has caused three problems with me. Firstly, at the age of 36, I am only just starting to figure out what I want, need, think and feel - I've never considered myself before and didn't really exist outside my mum. Secondly, I was taught that everyone else was more important than me, so any request made me feel like I was being selfish and I always thought I was in the wrong (for example, if someone bumped into me in a shop, I would apologise to them for being in their way). Thirdly, because I have this instinctive way of knowing what people want I assume everyone does - but the reality is most people need clear, specific communication because they weren't raised to operate on some sort of telepathic level.
I am finding my way through all of this and getting to a point where I can communicate my feelings and my needs to people. A great thing my therapist taught me is that you have to trust other people's ability to say no to you. So to use your example of asking Dr G to open the board again - my T would say, instead of worrying about whether your request is reasonable, ask the question - politely, obviously, but trust in the other person's ability to say no to you. So if you had asked and it wasn't possibe, Dr G would be perfectly able to say, "Sorry, I can't do that". That's his right to refuse a request - something else you aren't taught when you grow up with an N!
I've found this has helped me a lot - I can ask someone to give me a lift now and trust that they will tell me no if it isn't convenient, rather than worrying myself silly about whether or not it is appropriate and eventually not asking because I'm too worried about putting them in a situation they don't want to be in. Similarly, I had to tell a friend recently i couldn't afford to buy her a birthday present. I could never have done that a year ago; I'd have borrowed the money rather than not buy something. But I trusted in her ability to (1) value our friendship rather than basing it on what I buy for her and (2) being able to tell me if she felt hurt or upset by what I'd done.
It takes practise and I do fall back into old habits but it's getting easier now and I think the more you do it the easier it gets. I hope something in there helps a little bit

And try really hard not to feel ashamed! What happened was a simple misunderstanding that was quickly resolved and caused no problems on either side. Again, being raised to believe everything is your fault and a huge deal means we take on far too much over minor things that other people forget all about really quickly.
