Absolutely it's hard, it really is.
That's why setting a realistic plan that takes into account your own circumstances, is key. For example, assuming you're sedentary and haven't got other health issues, your TDEE (the total cals you burn a day) must around 2100 (ish).
Cutting very low may be too punitive for you. Maybe instead you focus on smaller cuts, accepting it will take longer but that you're more likely to stick with it. e.g. 1600 cals per day. If you exercise or moe much at all then you can up this.
If you know that there are 2 days a week when you tend to feel so tired you want to give in, or want to get a takeaway, then balance your calories so that you eat something like 1400 x 5 days a week and 2100 on the other 2. The net reuslt is the same as eating 1600 every day but this way you have extra cals you can call on, when needed.
If calorie counting isn't your thing then there are loads of other ways to achieve a deficit. e.g. just using a smaller plate and eyeballing 50% of the plate is covered by veggies, 25% by carbs and 25% by protein.
Or keto.
Or 18:6 to reduce your eating window.
Or 5:2 so that you only have 2 tough days a week.
One is not better than the other, except for where it is better specifically for you and your lifestyle.
Commitment is made so much easier when you think about "can I realistically do this for the long term?" Even easier when you think "can I do this for the rest of my life?". Because losing weight is really hard but maintaining that loss is really, really, really hard.
