I'm at the end of my own weight loss journey. Went through some of the same things that you have. I've lost 50 pounds in under a year. Just a couple more pounds to go.
Restricting my calorie intake is what really worked the best. Eating better is good but only goes so far, as you have already discovered. Cut the carbs (potatoes, breads, pasta) and sugar. Calories should be about 2000/day if you are exercising. You'll be losing a pound a week. Hard at first, but your stomach will shrink and adjust then it won't be so hard. Although there are some days that it can be difficult. Drink lots of water, no soda. Not even the diet soda. The artificial sweetener actually makes you gain weight. So watch out for that in your other foods as well.
