Difficulty finding a happy middle ground

I've finally managed to switch my motivation on, and start losing a little weight. I'm current around 105kg. The problem I'm finding is that it's really difficult to eat the suggested calories. It seems I can either overeat (which got to me where I currently am) or just go without. I can be really quite comfortable with only eating 800-900 calories per day (or far less), but I know it's too little. If I eat more, it's like the damn breaks and I feel super hungry and I start to struggle. If I eat really little, then my sugars stabilise and I feel good as well as losing weight. I'm super conscious about losing too quickly, rebounding, and gaining more back than I lose. Anyone else have any experience of this?
