Secondly, socialising (if and when we want to) is all well and good but it's often help with the practical things that we need.
I know from things I have been through in my own life that sometimes, we want to talk about issues that are affecting us without feeling like we have to make excuses for putting ourselves across or behaving in a certain way, stimming or worst of all - masking. Issues could include isolation, money worries, bereavement, travel etc. Or maybe, if we have issues with executive functioning, we might need more practical help with things like financial management, housing, writing a letter, applying for a job, making a complaint about a product, benefits and forms, mealtimes etc.
What if there were a bank of fellow neurodivergent souls you could connect with, either just for a listening ear or for practical advice on a topic that they themselves have good experience of and are willing to share with others. Many find benefit in just sharing their diagnostic experience and hearing how others have come to terms with their neurology afterwards. There is nothing more valuable than the experience and insight of other neurodivergent adults and of course, that doesn't mean everyone's ways of doing things will fit your way of being but you never know, you might just glean that nugget of an idea that you could try.
