I have a number of suggestions for you:
1) First of all, it is unrealistic to expect yourself to change ingrained habits all at once, but you can start to change them slowly. I suggest you commit to cooking twice a week. On the weekend, choose two recipes that look good to you. Check out GIF recipes, which can make it all seem much more doable. Make a list of things you need, go to the store, buy the ingredients for those two meals. Make one that night, and one a couple of nights later. Most recipes are designed to feed ~4 people, so you'll have a couple of meals of left overs, but not something you have to slog through. So you'll at least be getting some nutrients that aren't ramen, and you'll be learning how to cook (and what you like). The only way to get better at cooking is to actually do it. Girls like a man who can cook (or, at least feed themselves like a grown up), so consider it an investment in your dating game as well.
2)Do you live near a Trader Joe's? Because they have tons of prepared and semi-prepared foods to make cooking easier. Buy some pre-made salads or wraps and keep them in the fridge for when you are feeling lazy. They are only about $4, and they are tasty and have a lot of stuff in them. Check out the frozen section - they have easy frozen stir fries where everything is already chopped, and they come with a sauce. Pair them with rice and you have a meal. They have good frozen/prepackaged indian food as well. Also, they sell vegetables that are pre-chopped, so if the prep work is an obstacle for you consider that.
3) There is a reason college kids live on pasta. It's cheap and easy. Saute some onions, garlic, and ground beef, toss in some canned sauce, put over pasta. This one really will take only 30 minutes. Personally I would add some sort of vegetable to the sauce or have a side salad (again - check out the salad kits at the grocery store - they have dressing, toppings, and all the veggies you need), but that is because I want to live past 50. You do you.
4) Buy a rotisserie chicken at Costco or the grocery store. Pair with some roasted vegetables (Do you know how to roast veggies? toss with salt, pepper, and oil, spread on a baking sheet, bake at 400. It makes every vegetable taste 100x better. Trader Joe's has pre-cut roasting mixes) or mashed potatoes or rice-a-roni or whatever. Make a chicken sandwich later in the week, or add chicken to a quesadilla or a can of refried beans or to a salad.
5) Most people don't cook breakfast and lunch, but are still "making food at home". Eat cereal or microwave some oatmeal packets. If you are feeling fancy, scramble some eggs and make some bacon (also, an excellent dinner option). For lunch, make sandwiches. It takes ~2 min. If that's too much, buy some string cheese (or other cheese you like), deli meats, crackers, apples, carrot sticks, and hummus or dip, and just keep them at work (assuming you have access to a fridge). Eat those things for lunch. No prep required.
6) You are missing out on a huge slew of foods that take <10 minutes to make. Fry an egg, heat up a can of beans, and add hot sauce. Make a quesadilla. Pour chips on a baking sheet and sprinkle with canned black beans, canned corn (drain both), and shredded cheese, and bake at 300 til the cheese melts. Top with sour cream and salsa and you have nachos. Heat up a can of soup. Make a breakfast sandwich out of two eggo waffles, a fried egg, and some bacon. Buy yogurt and add granola or cereal or nuts. Can of chili on a baked potato. Buy lunchables. Peanut butter on toast. Beans on toast. Eggs on toast. The super market is literally full of convenience foods that are not ramen, but you have to try and branch out.
7) Do you have any friends/siblings who like to cook? Tell them you want to get better at cooking, and ask if they'd be willing to come make dinner with you occasionally. You'll learn new things, and it's more fun to cook with (and for) other people. Believe me, people will be happy to come cook with you.
8) Save podcasts you are really looking forward and listen to them while you are cooking. It gives you an incentive to get started when motivation is low.
