Kleinia obesa

Bought this plant a few years back, it didn't look like this then. But I guess you know that, right?
So what did I do wrong?

 

 Some time I wish some plants would just die.

Arid Lands was this to say about Kleinia obesa

"From southern Yemen, this species is sometimes listed as Senecio deflersii. The form of this species is similar to a giant green pickle, only this pickle produces bright yellow flowers in the fall."

My giant green pickle is looking more like a raisin.
