An obituary is a formal ‘public resume’ of a life that has now ended. It can include details like the place of birth, location, work and the names of the surviving family members. It is like a LinkedIn profile along with the Facebook profile picture.
A eulogy(pronounced You-luh-jee), by contrast, is about sharing memories, stories, quirks and the human element of the deceased. It captures the legacy and impact of the deceased.
A little bit of fear is normal. In fact, fear helps you instinctively protect yourself from harm. Your fear might help you to recognize when you're about to do something dangerous and it could help you to make a safer choice. But, you might find yourself fearful of things that aren't actually dangerous, like public speaking.
