Couldn't say about seizures..I've never really paid much attention to the twitching; I'm aware of it, but I guess it's low on my list of concerns. Do you have a regular GP? That would be the place to start. Find out if there's a physical cause, but also see if you might need meds for BP. I have a hard time separating the physical from the mental because they are so intertwined. A therapist (as opposed to a psychiatrist) isn't a medical doctor, and most likely would refer you to your GP anyway. IMO, self-diagnosis can be disastrous...I put off seeing my GP for ages thinking I had carpal tunnel and ended up with two metal plates in my neck..you just never know..
