I have had that as well. I have pseudo seizures too.

Isn't it anxiety and all the blood rushing around what creates that sensation? Maybe try grounding yourself by looking around yourself and stating things you can see and hear to yourself while taking some deep breaths

I've spoken to my therapist who explained her understanding was that anxiety attacks are only emotional distress, whereas panic attacks have the physical symptoms. I don't know if this is right though

Psychogenic Non-Epileptic Seizures (PNES) As the name suggests, this type of seizure (formerly known as a pseudo-seizure) is not related to epilepsy. These can occur at any age, but most commonly occur under age 55, explains Epilepsy Ontario. It can be tough to differentiate psychogenic and epileptic seizures, as the features can be similar. It usually takes a neurologist (a specialist in the study of nerves and seizures) to make the distinction through electroencephalogram (EEG) recordings. It’s important to make the distinction, because anti-seizure medications are not effective for psychogenic disorders. Some patients with this form of seizure may have experienced trauma earlier in life, notes the organization.

I was diagnosed with Pseudo seizures along with Syncope. Syncope is also known as fainting. This is a temporary loss of consciousness with a quick recovery.

I think it would be best to ask a doctor about this before assuming that it’s something psychological.
