agree, you need to book an appointment with a neuro, not a GP. A GP will almost always see anxiety in your case, and want to medicate you for that. if the meds for anxiety dont work, he will then jump to the next conclusion. Its better to go see the big boy himself who specializes in brains and brain disorders such a seizures and other disorders of the brain. Ask your regular MD for a referral to one, tell him it would make you feel better to cover all the bases on this one.
I hope you feel better
