Have you asked yourself what the danger is in letting them out? Keeping them in is .. a misperception of control (of the chaos, when little), fear of something too (of not being seen or validated if in emotional pain? fear of falling into deep dispair? fear of.. )

What do you see would happen, or what would the consequences be if you let them out?
Can you envision crying and having compassionate thoughts about yourself, similar to how you might respond to someone else in distress?
