Seizures

The past few weeks I started having these odd psychosomatic complex partial seizures. I get convulsions and distorted thoughts/speech. My doctor isn’t sure what it is because one of my medications helps prevent seizures. It sometimes seems like a psychotic episode- I get convinced something is trying to escape through the top of my head and my speech doesn’t make sense. Most of the time it sounds like bad poetry. I even posted something here during an episode that didn’t have full convulsions. Some people think it’s anxiety, but that seems pretty far-fetched. I don’t have symptoms of anxiety or anxious thoughts before an episode. I get anxious during an episode because I have no control and it’s scary. I really don’t know what’s going on, and my doctor isn’t inclined to be helpful. Does anyone experience this too, or know what it is?
