Is it perhaps the medication you're taking. Some epileptic meds can be mood altering.
It could be medicine causing it. Some seizures are mood controllers and some are not. Also, I've learned lately, that it's the diagnosis and symptoms we experience with it. Besides seizures can come anxiety, depression, anger, etc... alot of mixed emotions. I suggest talking to Dr about it, as I had to get on a mood stabilizer but still experience alot of emotions, now trying psycho therapy and CBT therapy
Ask your doctor for anxiety med or something to help the anger
Ya some medications have messed with my emotions too. And it isn’t fun
Great info will do asap Ty Gail
