CS6 to Creative Cloud

I bought Adobe CS6 in 2013, and I prefer using it because I live in a remote part of Alaska so don't always have access to a decent internet connection to use Creative Cloud. I also am on partial disability, so can't afford the monthly license for Cloud (my insulin costs about $2,700 a month, and I need it to live). Are there ways to continue using Creative Suite? If I update the operating system on my MacBook Pro to OS Catalina it looks like I no longer will have access to my CS6 program. But if I don't upgrade I get this kernal_task problem that gets the fan sounding like a jet taking off and my computer slows way down.
