It is having trouble supporting its own weight, and I am hoping that cutting off the top (where it starts to droop) would let it grow more full, rather than just tall. Would that work? Does it work with all plants?? I have a few that seem to have this issue.
I'm afraid cutting off the top from where it leans over will not solve the problem, because the problem is insufficient light - you will notice that the plant has the appearance of stretching and leaning over to get as close to daylight as possible.
You could try moving it to a brighter spot, directly in front of a window and as close as possible, with the leaning part turned in towards the room - hopefully, the plant's desire for light will mean it straightens up.
