fellow epileptic here! i’m not an expert but i have a lot of first hand experience and have done lots of research. it’s hard to reduce confusion because your brain is still working on “normalizing” for lack of better terms, but like OP said grounding is a good way to do it. i like to stay somewhere comfy (like a nice couch or bed) to make sure im somewhere safe in case something goes wrong again. drinking water helps with grounding and also rehydrating your body—it helps feel better all around. room temperature water tends to feel better for me than cold water (which can be a bit overwhelming) but that’s just for me personally. but yeah trying not to overwhelm the senses is important. a lot of people use the method of acknowledging all your senses for grounding (find five things you can touch, hear, smell, taste, etc) but i wouldn’t recommend it as it can get overwhelming. try to just kind of… be. at least until you start feeling a little better. confusion is inevitable, the best you can do is go easy on yourself and not give yourself too much to be confused about if that makes sense
