Help!!!

Once it breaks there isn't much anyone can do to help. It will either heal and survive and send out new growth or it won't and it will die. Preventing the breaking in the first place is what needs to be done. But it is a leggy plant and sometimes they just can't support the weight of the leaves.

I assume that is some sort of rag or something tied around it? And tape? They will only interfere with the healing process so I'd recommend removing them. You can carefully slide a pencil or a thin strip of wood into the soil alongside the stem to help support it but you have to take care not to do more damage trying to fix it.

Or you can take the whole plant and transplant it into a very deep container burying all that stem to above the break. It will try to develop new roots and send up a new shoot.
