Hello, I am Kitt. Please accept my sincere sympathy at the death of your sister.
There are very few things in life that are harder to face than the sudden death of someone you love. The loss of their life can make you feel like you have an enormous hole inside yourself.
You did all you could for your sister so please do not blame yourself for her death. In about seven out of ten people with epilepsy, no cause can be found. You were a wondeful sister and over the past months it sounds to me like your sister had the best care possible.
Now is the time to take care of you, grieve for your sister in your own way and please know we are here and we care. My prayers for you and gentle hugs.
