Transient Epileptic Amnesia (TEA) with undiagnosed adhd

I am as 69 year old male living in the Wisconsin Northwoods with my significant other.
I have TEA, diagnosed and treated with Lamotrigine.
This medication controls most all of the major symptoms of tea, I believe.
I believe that I have adhd, lifelong, undiagnosed, but have had and do exibit all the symptoms.
My current issue is this; from my significant other only, I take almost all corrections, mostly about irrelevant topics as criticism and respond angrily, as if I'm being treated like a child.
This is creating a significant struggle in our relationship.
A Mayo doctor has suggested the HABIT program but I see this therapy deals with dementia-alzheimers patients and their relationship issues.
Im not sure if this program will help our situation and we are struggling about where to seek help.
I have had counseling sessions for several years, by myself and with my significant other. The therapist stated that her experience-expertise wouldn't help our situation.
We're seeking support and suggestions
on what actions to take at this time?
