Oh, love!
You need help. Your guts are messed up because of all the processed food you are eating. That's why you feel bloated.
It's fine not to eat breakfast if you don't feel hungry, but it's not fine to spend the rest of the day snacking and eating crap.
Just as an example, (and I'm not showing off !) a typical day for me is...
Full fat Greek yoghurt with blueberries and seeds at 8am. Or a boiled egg and 1 sl toast.
Lunch- either homemade soup, or cheese and fruit, and sometimes some oat cakes, or some kind of salad (leaves, tinned fish, cheese.)
Dinner - grilled or baked fillet of fish (cod, salmon, haddock) or chicken fillets/ thighs, with a lot of veg (often do roast veg - peppers, squash, sweet potato, mushrooms, aubergine) . Green veg every day- broccoli or spinach usually.
Dinner can also be a stir fry, home made shepherds pie, roast chicken dinner, vegetable curry, wholegrain pasta with stuff thrown in.
More greek yoghurt and fruit for 'pudding'.
Occasionally we have a pudding like once a week- crumble, or something I've made.
