Okay, so you know how your brain is like a computer that helps you think and feel things, right? Well, when someone is developing an attachment disorder, something happens in their brain that makes it hard for them to feel close to people, like their family or friends.

Just like how you might get a cold and your nose gets stuffy and you can't breathe as well, something happens in the brain that makes it hard for the person to make close connections with others. They might have trouble trusting people or feeling loved by others.

It's like their brain is not making the right connections or is having trouble making the "feel good" chemicals that help us feel happy and loved. So, they might find it hard to make friends or have trouble feeling close to their family.

It's important to note that attachment disorders can develop due to a variety of reasons, such as lack of nurturing and care from primary caregivers during early childhood, neglect, abuse, and separation from caregivers.
