I think you need to start learning a lot of things from scratch. They are just very different programs with different concepts and layouts. You can sure transfer some things over but I think it might be best to just start from scratch, skip through the parts you feel familiar with. Try some beginner tutorials like the donut to get some overview and then learn how you learn new stuff. Just maybe try to not to think of it as 3ds Max but different. Blender is a very different experience and not looking it as a migration but a new tool might ease the frustrations.
