Hi CrazyStress,
As my mental health suffers my memory becomes very poor. I have had memory problems throughout the last 3 years during which time my mental health has been quite disabling. I asked my psychiatrist about this and he said that it is the mind's normal reaction to having so much stress i.e. if you are focussed on your anxiety then you have less ability to remember. He also suggested that when we have a hard time with our mental health our mind does not want to remember so we forgot some things selectively without meaning to.
I would not worry about it too much.
