Yeah I've felt that quite often since I started on SSRIs - it's a pretty common side effect, especially when you're increasing or decreasing dosages. It can be quite annoying at times but in my eyes it's preferable to what I'm like when I'm off them. Try some mindfulness/meditation practices. Look up some videos on youtube, sit quietly and focus on the spoken words. Meditation is pretty much thinking about nothing but it's really helped me improve my focus and memory.
I'm on an SSRI and with this latest relapse of my symptoms I have noticed a bit of brain fog. I basically feel dumber and more forgetful. I feel like I can't spell right now!
I was kind of worried about it, but I spoke to my GP the other day and brain fog is a common side effect of anxiety itself too.
I've actually noticed it getting better as I'm improving.
