The cooking thing really hits home. I work in a high stress, banking environment at a fortune 500 company, and I eat out most days. I know theoretically how to cook, but between the time it takes to shop, cook, and clean, AND I'm doing well financially it's so hard to convince myself to cook. Living alone doesn't help either.
Get a slow cooker and have your groceries delivered. You can make delicious, nutritious 1 pot meals that last you 2 or 3 days a pop with minimal prep time and cleanup.
If you have the money (and it sounds like you have), there are quite a few recipe box companies which send you boxes of ingredients and recipes every few days. It's a nice stepping stone towards fully cooking for yourself as it cuts out the shopping/deciding part.
If you happen to enjoy it, cook. If you don't want to cook, you don't have to. It's also possible to eat healthily if you eat out, especially if you have enough money.
