You consider Sarah one of your best friends. You spent every day together in college. But she moved to a different city three years ago. You promised to stay in touch.
Today, you saw a photo of her on Instagram. A sudden wave of panic and immense guilt hits you. You realize you haven't spoken to her in eight months. It wasn't intentional. You didn't "drift apart" due to a fight or a lack of caring. Every single time she crossed your mind over the last eight months, you were either driving, in the shower, or working. You told yourself, "I'll text her as soon as I sit down."
Because your working memory cannot hold onto a thought without an immediate visual cue, the thought vanished the second you changed rooms. The result is an eight-month silence.
Now, you sit on the couch staring at her contact name on your phone. The guilt is heavy. The ADHD brain begins to spiral into Rejection Sensitive Dysphoria. "I'm a terrible friend. She probably thinks I don't care about her. If I text her now, she will be angry that I waited so long, or worse, she will ignore me."
To avoid this hypothetical emotional pain, you lock your phone and put it away. You just ghosted her again, not out of malice, but out of sheer biological anxiety.
