I did get an MRI, but nothing stood out and I have not sought the opinion of another.
I think that my issue is not my brain, but my mind. Of what little I know of the brain, I am a strong believer in the importance of the environment and 'neurons that fire together wire together'. Which leads me to the belief that normal people must spend a lot of time replaying events after they happened in their mind, which is something I cannot do. Can I remember I met Bob and we talked? Yes. Can I remember any details of what we talked about? No. I cannot replay a conversation in my head whatsoever. If you and I talked about programming, I would forget everything you said but might remember you mentioned a cool library, but I will forget its name.
I have to admit, I just get depressed when I start to take notes. I feel like these are basic things I am supposed to remember, and I tell myself I can remember them, and I should, and I just need to put the effort in. If I have a meeting, I take bullet point notes because I cannot write quickly, and after getting in front of a computer I try to recreate as much as I can from the bullet points. If my boss tells me to do something, I have to hope it is in written communication so I can refer back to it completely. I am basically making every excuse to not take the small steps like proper note-taking and doing Anki to stay sharp and generally just do not wish to think about myself.
When I do take notes, I notice I have a deep seated fear to read them again. Something about reading my own writing revolts me.
