I'm not going to claim to know how time and anyone's ability to view it works. There have been reports of many throughout history who have been known to see the future. Did you? It sounds that way. I can never know, so I'll take you on your word.

As for the source of the vision, how can you really know? My thought is to search your soul and ask yourself if you want to proceed before doing anything. If your soul feels it is wrong, it is. Could you have been working with a God impersonator? I struggle to believe in an omniscient being who develops a strategy that places you on the path you went down. Of course I'm not omniscient but it doesn't seemed to have served your best interests.

The source of my being has no commands. There is only the law and it is what it is. You can't go around it, you can only work with it. We are all one. That's it. The laws of physics follow this law. The laws of mathematics follow this law. The laws of nature follow this law. Only man who invented religion, business, etc deviates and attempts to ignore and bypass the law.

Lets say for kicks your seizures affect your temporal lobe. It has been shown when the temporal lobe is stimulated electrically people are suddenly mystical or spiritual. They have visions. They have severe personality shifts. The psychosis portion of your experience could be due to lesions or other damage there. I'm not saying you didn't speak with God, but we filter every piece of information that comes in. We are biased beings. Our data is incomplete. There is much we do not and cannot know. There have also been many Gods and God impersonators throughout history. Rationally speaking, it makes sense that we keep that in mind when we interpret what we see in visions.

I had them too. Not to the extent you have by any means, but visions. I try not to get too attached. My belief is I am able to assist in the creation of my own life and my will is strong. I'm not laying down and taking it if a vision says I'm headed for something I'm not down with. That may be a pointless battle, but I'll fight it anyway. I couldn't live with myself otherwise.

Visions of the past are a bit easier to deal with in my opinion. They give you a clear choice. Assume it is true and work with it or assume it is false and ignore it. I'm a why do one or the other when you can do both girl, so I say who cares if it is real or false...it is in your consciousness now so you might as well deal with it. There are infinite routes of dealing with that sort of violation. It starts with acceptance and can then take many turns. If you want to find peace, it should probably end with forgiveness.
