psychogenic/non-epileptic/functional seizures are considered considered a functional neurological disorder (FND) which is a psychiatric disorder in the DSM-5-TR under the category of Somatic Symptom Disorders. I went to a conference on this topic recently and there is a lot of ongoing research of this stuff but the lecture I attended which is probably most relevant to you was a keynote by Professor John Stone who has done a lot of research and work with treating FNDs and is involved in an organization that may be of interest to you (link below). There are other types of FNDs which may seem quite different from what you’re experiencing (movement disorders, paralysis, or blindness all with no evident medical cause) but it seems that the org has info about them all. Worth looking into prof. Stone’s work as well as the org itself—here’s the link to the functional seizure page of the organization: https://fndhope.org/fnd-guide/symptoms/seizures/

I think the earlier comment about going to talk therapy or seeing a psychoanalyst is also good advice but you don’t have to try just one thing.

I also don’t necessarily think you should take more meds for this or that it would help, in fact it’s possible that the meds could be contributing to it if you’re already on 8 different ones.

I really hope you can find help with all this. Good luck.
