My aunt lost the "star" of our family 3 years ago and she has still not gotten over it. She watched over me for a few months while I was looking for a place to live and she would take me to the side, guide me away from bad things that she saw in me that my cousin did. She would not be able to finish telling me about what I would do cause she would cry at his name. She has not fully recovered in three years, but it sounds like you are better off than she is. I have not had this experience yet due to nobody besides my cousin passing, however I did watch my dad have a seizure on Thanksgiving two years ago. I remember holding his hand, yelling his name, and he would look at me like he didn't even know who I was. There were just sounds of pain, looks of pain, and confusion on his face. Whenever I think about this horrible event at night it almost brings me to tears and even with this post it has brought me close to tears. However the only advice I know of is to talk about it with close people to you. Hopefully time really will heal wounds, but they can only heal wounds so much before they become scars.
