Is there any hope?

Hi! This bad boy has been thriving for the last 4+ years both outdoors and indoors (upstate NY summers), but there have been some catastrophic changes in the last couple of weeks. An animal or the wind knocked the pot over, so I had to transition to a smaller pot (it's not tiny by any means), and I had to move it inside at the same time, and it's gone from constant 60s and 70s through October to 30s now. Weirdly, the leaves are drooped but haven't fallen off or changed color for the most part. Is there any hope for rescuing this plant? How would you balance being in the window for light vs it being too cold in the window? Thanks!
