For example(s), when I was in 8th grade, I read the entire Redwall series to comfort me during anxiety attacks that caused me to stay home from school for weeks. Now that I'm older, I re-read the series to give me comfort when I'm dealing with a rough time.
I'm also just about to re-play Jak 2 and Jak 3 on the PS2. When I first started being home-schooled in high school, these were the two games that I obsessed over and spent so much time playing to take my mind off everything. Just the thought of playing them is giving me a comfort I can't explain.
What about you?
