Start with making a better list of skills to learn. Identifying edible foods is nowhere near skill #1. I occasionally pick berries, and even more rarely catch and eat a fish, but you can have decades of wilderness fun without ever eating wild food.
So, step 1, read some trip reports, books about long trips that relate to your planned excursions. For example if you want to canoe camp, read about a long and epic canoe trip somewhere near your target area (the Amazon is very different from Northern Ontario.) If you want to hike, read about a through-hike. If you want to climb mountains, read about mountain climbing (but don't read about Everest if you want to do something around Tuscany.) From these you will develop your actual skill list.
Step 2, do some of this in a supported way. Ideally, get someone to take you on a short trip where you can practice things and get help if you're not doing them correctly. If that's not possible, practice when you're not on a trip: put the tent up inside, cook on your camp stove on your apartment balcony, try packing into your backpack and walking around the block with it for an hour. Here if you can't do something properly there's no harm done, you just return to your safe warm house and your fridge full of food. Make a packing list, and then for a few days try using only things that are on the packing list. When you reach for something you hadn't listed, you can add it to the list.
Step 3, do some of it for real, but still somewhat supported. For example, when you canoe in Algonquin Park, the portages are all marked with large signs. You can generally find them by just observing where the 5 or 6 other canoes on the lake are headed. This means your map skills don't have to be amazingly great yet, you just basically need to know north from south. Also the campsites are marked (and on maps you can buy) and fire rings are already built. This means "Choosing a safe place to camp" reduces to "evaluate if you would like this camp site or want to keep going to another one." This should be a trip with at least one other person, even if they too are a complete beginner. Solo camping requires you to carry much more weight and requires more skill.
Through it all, keep reading - "how to camp" books if you like, or just inspirational stories. Do small practice trips. Three days without shaving or brushing your teeth won't kill you, and next time your packing list will be a little more complete. You will learn how to get your tent up quickly, and what time you have to start making dinner so you're not eating in the dark. You'll spend the night somewhere buggy or noisy or otherwise non ideal, and next time you'll choose a better campsite. You'll see some wildlife but do something that spooks it, and next time you'll do better. As you get more skilled, you can take longer trips. And at some point you'll realize you're getting good at this.
