Glad you're being thorough with getting checked out.
I have PTSD with horrible panic and anxiety.
All I can say is talk it over with your doctor and the two of you can draw up a treatment plan.
For myself, Im not getting on that merry go round again.
Im exploring all other options.
Take care of yourself and rest until you get your tests.
If youre anxious about having another siezure just make sure you keep your phone charged and near you
But the best thing you can do is relax.
