Thinning Stem - Prayer Plant

Hi! i currently have a prayer plant that i just repotted—and i noticed that half of its stem was basically down in the soil. i moved it up, and now the stem won’t hold the plant together (the bottom is quite thin). it keeps drooping and i don’t know if i should repot it again, or if i should just wait for the part of the stem to strengthen. The plant hasn’t grown any new leaves in a while, but the one in the back is basically all brand new and has a way thicker stem. I tried supporting it with thread and toothpicks (you can see in the picture), but i’m not sure if it’ll hold up. thoughts? thank you!

As long as the stem isn't damaged too badly she should recover. I would advise a bamboo stake or dowel rod to offer support along the branch, rather than one spot.
