Overcoming the anxiety of downsizing and hiring a full-service relocation crew

Hey forum family! After living in the same suburban house for nearly twenty years, my spouse and I finally decided to downsize into a modern downtown condo. While the thought of a fresh start is thrilling, the actual prospect of sorting through decades of accumulated belongings, heavy oak furniture, and delicate heirloom antiques is giving me serious panic attacks. We originally thought about renting a box truck and handling the physical labor ourselves with a couple of friends, but looking at our basement workshop and massive bedroom sets makes me realize we are completely out of our depth. Has anyone here ever transitioned from a large family home to a high-rise apartment and used a dedicated team to manage the heavy lifting? I would love to hear how you managed the logistics without losing your sanity.
