Does anyone else do this, and does it ever stop?
I analyze all my interactions after the fact but mostly just because I can't keep up in realtime...I'm sort of just playing catch up.
I tend to only analyze conversations to an extreme degree (well...the bits I can remember...and for me "extreme" means way longer than an hour, means like days weeks or even years.... although not constantly nor continuously to the exclusion of other thoughts and activities, and not with the thought I absolutely must have done something wrong) when they seem significant at the time and also seriously -- to an abnormal degree even for me-- confuse/puzzle me. (Confusion is normal/standard for me but confusion comes in degrees, and sometimes it matters while usually it doesn't.)
Or (exceptionally rare this happens:_) when all, or (more often:_) pieces of conversations are stored clearly by chance (by chance generally means during rare moments I am not in sensory overload -- at those times literally everything about what I experience is recorded very clearly for no particular reason); But don't seem significant at the time....yet come back to haunt me occasionally when years later something clicks in my brain and I understand something (or many things) in retrospect I was clueless about at the time.
I don't have the beating myself up or convinced I have done something wrong aspect.
Although searching for wrong things does happen when an interaction seems to have (or definitely has, without any doubt) gone wrong in a very troubling way and I don't know why. (ie people have clearly
gotten upset with me, or clearly taken something very strange-to-me and baffling from what I've said)
And actually the insights I sometimes gain from analyzing interactions have mostly just made me want to talk more and helped me in future interactions -- talk more to correct the endless misunderstandings (most of which are really not my fault -- usually they are nobody's fault) and to practice.
I wonder if it may be that if you long for connection with others but give up because in the absence of constructive and honest feedback you assume you did something wrong, if just giving up and never trying again might actually make it worse -- make you feel more alone for sure and also make it easier to convince yourself you can never say anything "right"? -- which I don't believe is true....
Because right now you say that you have the sense of the interactions you have being pleasant, and how nice people are -- which I don't think would happen if things were always going badly...? It seems from what you wrote that these positive things counteract the sense/fear that you have done something wrong....maybe it would help if you consciously focus on the positive parts. Try to logic your way out of the social anxiety....
And even if you did in reality upset or offend or confuse people literally every time you opened your mouth, my opinion is that others should try to help you not condemn and shun you...someone who is constantly saying confusing or upsetting things likely doesnt mean to, or just knows no other way to interact with others and needs compassion and help -- and more practice not less.
Maybe you could start asking select people who are trustworthy and who you know well how you come across? (My further advice is don't ask everyone...most people are weirded out or confused by it... I never thought anything of asking such questions until I was told they tend to not be taken at face value.)
Or perhaps see if you can seek out some counselling (I know lots of things might make this impossible and it may not be the right kind of solution for you - no assumptions just an idea) specifically to get feedback on your social communication and help with this particular issue? If a professional says you are fine, perhaps it would reassure you? And if they say you are not, hopefully they would be the sort of person who could give you helpful feedback and individualized solutions for counteracting the self-doubt and for clearly identifying what kinds of things might actually be i appropriate or likely to be taken badly...help you creat a bit of guide so you aren't left just always wondering and afraid and down on yourself.
