Ahem, medication does not 100% cure it 😅 particularly when it's wearing off it tends to come back. Or if I'm in a state of higher emotion e.g. anxious or excited.
And actually - I do think it is related to having a disorganised inner monologue. I definitely have one, but it's very complicated, a bit like a pub with loads of simultaneous conversations and music in the background. But everything is fleeting and difficult to hold onto. I find it hard to manipulate thoughts in my head, I have to voice them out loud or write them down so I can "look" at them, otherwise they are too quick and they have gone. I can also tend to sort of verbally process things out loud, which sometimes stresses people out because most people don't verbalise the processing part, they just verbalise the conclusion. So if someone doesn't realise I'm processing (and I don't usually realise I'm doing it, so I can't warn them) it can sound like I'm contradicting myself or giving dozens of suggestions when really I'm running through each idea for suitability, but out loud.
Agree with the techniques of reflective listening or asking questions. One thing I picked up from teaching language classes is that a good exercise I used to use in a smaller class (2-4 students) was to get each student in turn to speak on a simple prompt (e.g. what did you do at the weekend?) but the magic was that each other student had to formulate a question to the other while listening, then ask that question. It always produced such interesting dialogue and I do actually use it as a listening technique myself.
Also, I think because I don't have much in the way of brakes/filter, I probably used to ask really intrusive questions as a child and must have been told off for it, because I had this real sense that asking questions was rude and I must never ever do it, I should let people decide whether they feel comfortable bringing up a conversation topic. But that leads to very one-sided conversations where people are asking me questions instead and/or awkward silences that I feel the need to fill, or I wouldn't have a good way to direct the conversation in a direction I'm interested in without just interjecting some random, connected (to me but not necessarily to others) thought. It's basically an immature communication style.
But actually as an adult, I have realised that actually, people also consider it rude if you don't ask questions, it is only intrusive questions which are unwelcome. With a more mature perspective, I DO know what is an intrusive question and so I can ask whatever questions I like because I am unlikely to go over that line accidentally. This has been an utter revelation and has transformed the way I have conversations because I'm actually interested in the response and so I want to listen and not interrupt.
