I seriously cannot learn how to script. What do I do?

If you want to take the most leisurely route, you can start learning programming concepts with an easier language. Languages like Basic exist for this purpose.

I also recommend taking actual C# classes and reading actual C# books rather than just doing tutorials. Just keep in mind that there are some differences between how Unity uses C# and how C# is typically used (with the .NET framework). But since you seem to have a good grasp of Unity apart from the C# scripting, I think you'll be all right.

A lot of people get stuck in this spot (there's probably a name for it at this point) in their programming adventure where they can readily read and understand most code you put in front of them, but they aren't able to create the code themselves.

I'm convinced this is due to the misconception on how the programming workflow should actually work. My compsci teachers, throughout my degree program, asserted that programmers spend ~90% of their time THINKING about writing code. Breaking down your problem into simpler ones, figuring out which structures and patterns work best, naming things, justifying decisions. Then once the general idea is all fleshed out (if not for the whole program, at least for a single module or class), you can worry about the details of how exactly to write it all down when you sit down to code.

This approach has worked pretty well for my classmates and I.

Maybe that workflow isn't conducive to gamedev. I'm really not sure. As far as learning your language of choice (this applies to pretty much any language), so long as you have the basic concepts of programming understood (variables, flow control, inheritance and polymorphism if using OOP, lamdas, callbacks, etc.), reading the language specification/documentation can answer TONS of questions.

I'm finishing my degree this semester and just last night I had to look up "c++ stoi" because I could't remember what value was returned when you try to convert an empty string "" to an integer. You'll never know it all. You'll always need a reference (or stackoverflow/unityanswers). Don't feel too bad about it.

Whew, that was longer than I meant it to be. Sorry if it's not helpful.

First things first. Read and understand the documentation of Unity It will help you understand what will you do in your codings Link of Documentation below https://docs.unity3d.com/Manual/index.html

Learning C# really does consist of the basics of what are variables, objects, classes, and other concepts. After you learn the basics try reading other people's code and understand what it does and how it works one line at a time. Then try to mimic that in your code. TBH I'm still learning a lot about programming in Unity3D C# and there many advanced concepts I need to learn. But my advice is after you grasped the basics that those tutorials provide, dive right in and refer back to those tutorials if you get stuck or ask for help.

Also, if programming is a challenge for you then you may want to look into Unity Playmaker as an alternative. You can find it in the asset store. It allows you to code via blueprints without ever writing a single line. I tried it myself and thought it was handy but there's still a learning curve. I come from a programming background and between Playmaker and writing C# myself I prefer C# as a personal preference.
