I agree that you should not let you stop, but on the other hand there is a serious responsibility put both on you and on your buddies when diving with them. You then risk not only your life but also that of your buddies. An unexpected stress or trauma situation can certainly happen also during diving, so knowing that you can react on it with a seizure is certainly something the buddies must know, and they also need to know how it looks like, how long it takes, how to treat it. They must be sure they are able to handle it, or even better (if possible) to recognize the symptoms before it happens, or the situations when it happens, so that they can either try avoiding it, or to bring all of you to safety before it gets really bad.

Having some additional safety equipment in place would be probably also recommendable - the freediving vest, or the freediving buoyancy belt from Zealog would be probably quite good help for such case, but at least a float, buoy or some other support may be needed. And of course, if there are any medicaments or tools needed for treating the seizure, it is necessary having them with, and it is necessary that the buddies can apply them immediately.

I think it would be a good idea to drill the rescue with a simulated incident - simulating the seizure both under water and on surface. Only then you can tell whether one or more buddies are able to handle it, or whether you need some additional measure to assure the security. Consulting the doctor or getting an advice from someone who is used to treat seizures in extreme situations would be also a good idea.
