Hi Pebbles,
I should imagine this is harder if you have never had memory issues before. I have always had memory issues, so now I have a convenient excuse! (Just having a meno moment!) In hindsight, I suspect I have had aspects of dyslexia and have had to work that much harder than others to gain qualifications. The realisation came with having 2 children with dyslexia, one severely, who has just graduated with a degree. So if you really want to carry on with gaining this qualification, then don't let memory issues get in the way. It is nothing to do with intelligence. However, you need to really want to do this and it sounds as if you are not sure. Maybe research and soul searching into what you want and what other options are out there for you.
As to worrying about whether you have been stupid in a meeting. This is a self esteem issue. We are our harshest judge. Most people are too busy judging themselves to be judging you. If someone are critical, it's because they are reacting to issues in their lives that have absolutely nothing to do with you. In other words, it is not personal. If it feels like it is it's because you are reacting from your own issues from the past. Just do your best and that is good enough. And if you make a mistake, well that's just being a human being. Be like my inspirational son who has failed his way to success! Ju Juxx
