I have a poor memory for a big part at the moment... actually over the bigger part of a year now. It's also when my asperger's came back more prevalent... it's when I went to the therapist at first for a depression of sorts and went on to get my diagnosis 6 months later, with results 4 months after that.
But yeah... my memory, my skills, everything in daily life is kinda lacking, mostly because of stress and anxiety since I have no clue where my life is going right now.
I don't know if that's actually Aspergers related or just general stress and anxiety, but it pretty much fits together since my situation at the moment, seeking support at social work, filing for disability is moving on, very slowly since february 2011.
I think I can also add that when I was a child, my memory was totally off. They thought I was well below average intelligence, and thus they barely got me in high school with average grades... barely passed that with a lot of stress and all. I got it more "under control" from halfway in my teens I guess, until last year... surely my aspergers was there in between but it just wasn't prevalent, no one was around me, I got my tuition fees for college, I just did whatever I wanted... now I'm at a point where it doesn't work like that anymore, and I'm falling back in old patterns, and as such slight depression and also... rather bad recollective memory issues. Not to mention that I am starting to suffer from slight disassociation issues in the past month or so.
I should also mention that I have ADHD, so a lot of stuff slips my mind, but AD(H)D is comorbid with aspergers sometimes.
So, no... I don't know if it's Aspergers related, but I do seem to have those issues.
I don't try to keep track of the concept of time... I have one clock around, and I rarely watch it. Clocks make me stressed out and I watch them more than actually do something. The most silly thing is that quite often I can guess time at any given moment, and be off... approximately 10 minutes... at any given moment of the day.
