You're not alone in this. I have Partial-Complex Seizures with an occasional GranMal (also Simple Seizures). When I do have the Partial Complex type Seizures, it drains me completely. What's worse is when I
have these type of Seizures, I have no idea that it has happened (other than what my family members tell me). Last year, I had one during church (of all places). I don't remember much of what happened. From what family members told me, I screamed (during the sermon!). The pastor was scared and didn't know what to do. The only thing I can remember of that day is sitting in church, singing and then having the urge to use the bathroom, so I left for the ladies room. Once in the ladies room I began to cry uncontrolably (not understanding why). The pastor sent one of the "Elder" ladies in to check on my well-being. The only thing I could think of is that I must of had a Seizure. My family confirmed this for me. I was exhausted the rest of the day. Ended up nursing a major migraine headache. Wasn't much fun.
Totally understand what your going through. If you need the rest and are able to do it, go for it. That's your body telling you you need rest.
Take care. Keep in touch.
