Agoraphobia is a big word that means someone is really afraid of going to certain places or doing certain things. The person might be scared of getting lost or hurt or trapped, so they don't want to leave their safe spot. It's like if you're in bed and the monster under the bed won't let you leave, but the monster is inside your head. This can make it hard for them to do normal things like go to school or the store with their family. But the good news is that a therapist can help them learn ways to feel less afraid so they can start to do more things without feeling scared.
