it likely wants to sleep. you should cut some of the leaves in half. and slowly put in a colder place where it can rest a bit. Then, when it is fully asleep, I would trim some of that long weak stem. I got a HC from hirts also, it was my first fig since I got my fever. It died to the ground and last spring it shot 2 shoots, they grew at most 5 inches, and went to sleep. their tips are green, but I kept them outside all winter, under a semi covered shelter to prevent snow and cold wind on them. it is cold out there. gosh, I hope yours recover, it is sad to see a tree with so much potential in such a sad shape.
