I've found my memory to be really shoddy lately. Moreso than usual. I think it might be a lack of mindfulness, my brain has all these other things going on in there and I'm not really being mindful of what I'm doing. I actually get kind of freaked out that I might have a brain tumour or something.
Sorry, my response probably isn't helpful, but this post about memory sparked this recent concern for me. Sometimes i don't know if I'm remembering something correctly or if I've made it up :/
