Leah Remini On Daughter's 'Bittersweet' Move to College: 'I Have Never Cried so Much in My Life' Like all parents of college students, however, the joy Remini felt was also tinged with sadness. "I have never cried so much in my life," she wrote after she and Pagan helped settle Sofia into her new dormitory. "I am only comforted by meeting other parents at Target who bonded with me over our mutual pain and pride," she continued. "It is the hardest thing I have ever done, and I'm still torturing myself with the idea that I might have pushed my daughter on the college track because I never got to go when I was her age," The King of Queens alum added alongside an old picture of the mother-daughter pair posing for the camera.

Remini, who currently attends New York University herself, then reminisced about how she and Pagan felt the same way when they sent Sofia to kindergarten. "Angelo and I sat in the parking lot of our daughter's school, crying like babies, and discussed pulling her out and homeschooling her," she revealed. "It is not easy to let go; change is so hard." In a separate Instagram post, the star shared a carousel of photos of her wallpapering Sofia's new room and posing for photos with friends and family who helped her make the big move.
