Why I'm scared of losing loved ones: Lost my older sister in a car accident. Someone was drunk driving (heard that on the news later) and crashed directly into the side of the car.
When I woke up in the hospital (most of the injuries were caused by broken glass as a result of the car window breaking, and a few shards hit me in the leg), my sister was dead from the impact itself.
We managed to get the car fixed afterwards, and the scars healed by the time I posted this, but the whole thing left me scared of losing the ones I care about.
