Please help with my seedling

ok so today i wanted to transfer my seedling to a smaller pot because the first 1 was to big and it was streching. while i was doing it i accidentally broke the tip off the root and now the leaves are sagging. what should i do.

What up? No one answering?That cuz you don't transplant to a smaller potTransplant to a larger potstart small
