MAJOR separation anxiety!

I knew that Seth has been going thru separation anxiety, but oh my is it bad! Daddy usually drops him off at daycare in the mornings and Seth is usually upset when Daddy leaves, but when I dropped him off this morning, he clung to me for dear life. At first he wouldn't let go of me so i just knelt down and held him for a while, finally when his grasp loosened up some, I tried to step away maybe 5 feet to sign him in and he immediately started crying and tackled my leg. Then when I tried to put his jacket in his cubby he began crying real tears! Once breakfast came I sat him at the table and sat with him for a few minutes. I then leaned in to kiss him bye bye and i told him that I had to go. He had to have understood me because he immediately started screaming mama mama as he held his arms out to me. I kissed him and said bye bye and as hard as it was to leave, I knew that I just had to walk out otherwise i would just be prolonging his misery and mine. Just writing this makes me tear up and miss my little guy! Okay, gotta get back to work now and make sure my mascara isn't running down my face!
