Hard to say, because over the last months everything changed significantly and I don't really struggle anymore. I'd say that my main problems are talking over the phone and socialising in a large group.
With the former, I worry about not being able to catch what the other person says, I just get so many clues from body language. People sound different over the phone. I'm sure I'm imagining this, but when they answer, people often sound taken aback and I misinterpret it as them thinking my enquiry is weird/off in some way. Plus, phone conversations to people you know always start with "hey, how are you", and there's the awkwardness of ending the call. Ugh.
With the latter, I sometimes fail to 'tune in' to the dynamic of the group, and after a few tries just fall silent and 'switch off'. Turn-taking in a conversation becomes really hard, with people having to raise their voice and talk over someone else if they want to say something. I start to feel like I have to 'demand' attention (which everyone naturally gets in a 1-2-1 or a small group), it feels pointless, I give up.
