@dcalciferol I used to help a lot of people get set up on Shopify, here's what I've found to be most useful:
1) Once you have your store access, go through every page in the admin area and experiment to see how things work (create a product, collection, etc then see how it looks on your site).
2) If you run into challenges along the way, do a google search. If you can't find the answer, then post the question in the forums here.
3) I've seen many people set up their store without any technical knowledge, you just have to invest some time. If you have the budget you can hire an expert (experts.shopify.com) to do anything you need. If you're on a tight budget, I recommend setting up everything you can on your own, then create a document with bullet points on the remaining things you'd like to hire out.
I've seen people start and launch their entire store without hiring, so it's definitely doable. I think your frustration might be holding you back (if you're writing in caps it likely means your angry / yelling, if that's the case, remember that anger is not useful when trying to overcome a problem, keep a clear head and positive mentality and you will eventually overcome the hurdles you're facing).
Another idea, if you're looking for more of a walkthrough guide instead of information, try Youtube. That can be a good way to see how to do things step by step and with visuals.
In my opinion, the simplest way to learn Shopify is to open your store, load some products, then do a test order. You can do that within an hour. Don't worry about things being perfect. From there start adjusting things as you want, and learning what all the settings do.
Anything you want to do in a Shopify store is accessible and with solutions online, you don't need to do any coding, just configuring settings pretty much.
