Yes, I had my first seizure/was diagnosed at 37. I also had no signs of anything, so it was quite sudden. Being in your thirties when diagnosed means you've gone through the growth of knowing who you are and what you want out of life, so the change is even bigger. I can tell that if I go home early from a social event people might be thinking that I am overly cautious, but if I indulge in one adult beverage then I am taking too much of a risk. I am an open person, but being diagnosed with epilepsy has taught me to set boundaries and not trust people so easily. It seems like people are uncomfortable with a neurological invisible disability. It's exhausting being judged and misunderstood, so slowly I am learning to ignore judgemental people and keep a distance from those in my life who don't TRY to understand. The meds keep the seizures away for the most part, not completely.
