Hey Blue,
I'm hoping you'll start feeling better with each passing day. I realize this will take time.
Sometimes when I'm feeling the way you describe, I do find guided meditations helpful. I use ear buds and close my eyes, hoping to focus. Sometimes, my attention wanders. When I catch it, I redirect it, which is good practice for me.
I often choose guided meditations on the topic of self-acceptance if/when feeling a bit down on myself. Other topics are great, too.
One of my favorite practitioners offering guided meditations is Tara Brach.

I realize you deal with some concentration issues at baseline and you utilize a stimulant med which helps with this challenge.
Any chance the current difficulty with concentration might be a Trileptal side effect?
In my experience, most meds in that drug class cause some "spaciness." Just my experience.
I hope you experience some relief soon.
Love ya!
