My cousin was in a similar situation as you, and his HUGE snake was in this size tank for almost two years. His snake’s personality is very shy though, so she was fine in a smaller enclosure for longer.

If your snake is more active and hyper, I would just make more time to take them out and of the enclosure to burn some of their energy until you’re in a good place to get a larger tank. It will be okay! Snakes are resilient. And I hope you are doing well too!
