So confused

Your best friend right now is logging. Log your food before you eat it or make a plan, enter it and see if it's going to work. A lot of us have been doing this for a long time and have mini calorie calculators in our heads. Eggs are a great food, about 70 calories each, lots of nutrition, good source of protein and will keep you feeling full longer. Full fat dairy, including cheese, you just have to watch your portions. Weigh and measure before you eat it. Nuts are great, 10 or 15 almonds, not a whole bag full are a great snack food. Lean meats, weigh out 3 oz before cooking and that's a portion. Supplement all your meals with lots of veggies. Fill your plate with veggies. Have fruit for desserts and snacks.

Mostly though, plan ahead. You seem to be making your food choices then checking later whether it was a good idea. You can look up just about anything in the food database and if you enter it and want to delete it and make a better choice just click the red circle and it's gone again.
