I could really use suggestions...

I do hope that someone can advise you but I am the same and hardly like anything healthy.

I won't/can't force myself to like stuff so I eat what I always have but just cut the chocolate out and smaller portions plus exercise and have still lost just over a stone in 9 weeks so am happy to stick to my diet,whatever works for you I say.

Well. Maybe try to get used to it gradually? This is how I managed to change my habits.
Previously I loved sauces, gravy, any crispy skins. And all of these together in one meal. Dinner without a meat? Such term didn't exist.
I knew that if I changed my habits too much at once I would stick to it very shortly. And after some time I would have a weak day and my zest would start to disappear.
So I explored recipes with less calories step by step. Slowly I was changing my eating habits, adding veggies, fish, reduce meat etc.
I cook my own meals to make sure that it will fit my taste. You have to "learn" new tastes. Your preferences will change slowly.
Otherwise you will try some dishes, find them unbearable to eat even in single serving, not to mention three times a day.

How do you get yourself to learn to like things you know are healthy and good for you, and that you need, but most of the time can't get past the smell or just do not like the taste of no matter how many different ways you tried it?

Probably can't. Any more than I can stomach coffee or butterscotch. Easier to work within what you do like.

So, you mention you like raw veggies -- that's awesome. Do you like any fruit?

What else do you like? Sounds like you've got plenty of carb options. How about proteins and fats?

that's part of the problem..there are not many proteins that I like. I know I don't get near enough in the protein category each day.

Sorry if this seems a bit in your face, but I don't like to focus on "can't", I'd much rather focus on "can" -- let's figure out what you DO like and work from there. Proteins covers a lot of stuff -- milk, cheese, chickpeas, yogurt, sour cream, steak (heck, beef of any sort), chicken, duck, pork. Doesn't have to be fish.

When it comes to calories, surprisingly, I didn't exceeded my daily limit. I measured how many calories I ate before the diet. Just to check how much I ate in regular. I admit sometimes it was too much, but then I had a deficit on another day etc.
The problem was the ratio of fat/proteins/carbs.

Well, as I wrote, you have to "learn" new taste. It's a bit like dishes you hated when you were younger, but now you like eating them.
If you have an approach that this meal is dreadfull/boring (or another negative association) then you won't be able to change.
Take little steps. Don't eat only veggies. In this way you will feel that you give up the food you like for this ruffages you are already sick of.
Maybe thick soups will be good here? I've found that many people, who don't fancy veggies and don't eat regular soups, really enjoy eating warming thick soups.
Or some sauce? Use a skimmed cream or a greece type yogurt and add some minced (cooked) vegtables, e.g. broccoli with onion or cauliflower, some seasoning. It would be a good dip.

I'd say, rather than trying to make yourself like foods that you think are gross, try different vegetables than usual and see if you can find anything new that you like. Also, try cooking vegetables different ways--steamed, sautéed, roasted, mashed, whatever floats your boat. Personally, I love vegetables but still think that veggies are gross. For instance, I thought I hated butternut squash until I tried it roasted in the oven. My family always boiled it and mashed it, and it just tasted like gross baby food, but roasted, it's delicious.

Also, try starting with starcher veggies, since you like potatoes and corn? For instance, sweet potato, just to mix it up?

There are some vegetables that I don't care for but I have found that cooking methods change the taste of them.

I don't like carrots that have been boiled or steamed but I love them roasted. Same with cabbage, brussel sprouts and others. I tend to like all of them when they are roasted. It also makes cooking easier because I can just fill a baking tray full...use a little olive oil and seasonings and just stick them in the oven.
