Why do I feel compelled to cry during meditations focused on childhood memories?

When I follow a meditation guide focused on healing the inner child or reviewing childhood memories, I inevitably start to cry intensely. The sadness feels huge and overwhelming, and I often cannot stop myself. I believe this is tied to old trauma. Is crying a sign that I am successfully releasing the unresolved energy, or should I seek therapy to process this first? My name is Tanvi, born on 5th June 1999 at 4:00 AM, in Chennai.
