First, congratulations on the weight loss. That is a huge difference there between those two numbers.
Second, leave that experience in the past. Often times we can unintentionally self sabatoge by making comparrisons to what worked before and then get frustrated that it isn't working the exact same way again.
My advice, stick with the basics. Weight loss is essentially a math problem. As long as you eat less, weight loss will happen. Now it gets a bit more nuanced and complicated but this at a certain level, but for now just focus on this. Stat away from extreme deficits also. While the do work, the boucle back from them can be hard for a lot of folks to control. Keep it slow and steady here.
So what do you do? You have 2 options which are really based on which works best for you, personality and adherence wise. First, set a calorie goal and some macro goals and try and hit them. The alternative is to do habit stuff, like increase veggie intake, water intake, protein intake, healthy foods, etc and not stress over calories and macros as much. If you are the type that like to feel in control and enjoys the measuring and data tracking, then spend a week or two tracking your intake and trying to hit those macro goals. Don't switch it up from day to day. Don't stress weight at all during this time. A lot of people have a habit of making adjustments here because they see the scale go up or down. The goal here is to just establish a baseline to work with. Consistency is what is important. On the other hand, if your more into the habit stuff and don't want to get bigger down with details.. then simply try and clean up your diet some. Increase water intake, increase protein portions in meals, cut some carbs out the plate and replace with veggies and work on avoiding junk food and stick with the more commonly known "clean" foods.
