Thanks for using the forum. I am happy to address your questions, and my answer will be based on the information you provided here. Please make sure you recognize that this forum is for educational purposes only, and it does not substitute for a formal office visit with your doctor.
Without the ability to examine you and obtain a history, I can not tell you what the exact cause of your symptoms is. However I will try to provide you with some useful information.
The face drooping that was noted to occur before your grand-mal seizure is not a sign of that you are having a stroke before your seizure. Seizures can be partial onset, in which the seizure starts in a specific part of the brain, and then may or may not spread to other areas of the brain, leading to a grand-mal seizure (the other type of seizure is generalized: it starts throughout the brain more or less at once). If you have a warning before your seizure, and if your face droops before your seizure, these indicate that your seizure may be starting in a specific area of the brain (likely involving the face area) then spreading to become generalized, leading to a grand mal.
Whether or not a seizure is partial (another term is focal seizure) from the onset helps determine which medications should be used. Dilantin is a good medication for focal seizures, but it has its side effects and there are medications with less side effects for long-term treatment of epilepsy. If you are having increased seizure frequency recently, possibilities include that your dilantin level is too low (which can be checked for with a blood test as I'm sure you know), that your seizure threshold has been lowered (this can occur with stress, as you mention, lack of sleep, too much alcohol, or infections such as a cold or urinary tract infection), or sometimes, people simply start having increased seizure frequency of unclear cause, and require the addition of other medications.
Turning blue can occur when the seizure involves musles of respiration. This is not uncommon with seizures; it is important to have family members ready to call emergency services if the seizure does not stop on its own within a few minutes (most seizures stop within 1-2 minutes, but a seizure lasting more than 5 minutes typically warrants treatment in an emergency room, since it continues on this is dangerous and IV medications would be needed to treat it, and in that case, the breathing and other issues involved in the seizure can be addressed).
People with epilepsy such as yourself are at a high risk of depression, and if you are irritable and upset lately, feeling down or having a low mood, it is important to discuss this with your physician as depression is treatable with medications and counseling, and it is important that you seek care for this.
If your seizures are focal (partial) in onset, and start in an area of the brain that is resectable, one option for you may be epilepsy surgery. If you are currently not being managed by an epilepsy physician (a neurologist specialized in epilepsy) this is recommended.
Thank you for this opportunity to answer your questions, I hope you find the information I have provided useful, good luck.
