Two.

She slipped away from reality. Every trace of her existence fading away. She was so fixated on other people that she started to forget about herself too. One day she came across someone's problems that was caused because of her. That was the first time she had thought about herself since she started the injections. That caused one person in the real world to remember her. Which triggered that person to ask someone else about her. Which led to someone else, and someone else, and so on. Soon everyone was thinking about her. Everyone was sad and scared and not sure where she was. No one could remember the last time they had seen her.

She started to see more and more people's problems being caused because of her. She needed to get out and talk to people and see what she was doing wrong. She realized she couldn't get out. She was stuck. She realized her dosages were running low. She decided not to take them for a day, maybe she would be able to slip back into reality. Then she would be able to solve other people's problems.

She watched the clock tick on, monotonously ticking, the sound was hypnotizing. She didn't notice it at the time, but the world around her was turning grey. The people were beginning to notice her. She wasn't welcomed there.
