Hallo
I have quite the same problem with my memory. I get so stuck on events happened and the days whereabouts that i just cant think of what had happened. I used to keep a diary and write 3 times a day and when night time comes i just cant remember writing

those stuff,but its my hand writing.
Sometimes are worse then others, But overall i actually have a very intellectual memory and can remember the smallest detail that others do not notice. I believe that im stuck in some dimension when my memory is so bad. It feels like im living outside of my body and watching myself from the top,like a puppet on a string. Thats usually when im starting a severe depressive state.
Sometimes i recover my memory of events and sometimes i dont. Its like my brain does not want to know certain things or that its too tired or lazy.
Exercise helps and also Ginko Biloba and Omega Vitamins. Try those thins or otherwise consult your doctor. i also like to play games that stimulate sthe brain like memory games,makes me calm and its a good way of entertainment.
Good luck
