Taking a diet “break”

I’ve been “dieting” (watching what I eat, aiming for around 1200-1400 calories a day) for about two months now. I’ve been getting discouraged I’m not seeing faster results and I have noticed I’ve had a dip in my energy levels, have been more irritable and just feel like i’m really dragging. I know my calorie deficit is more intense (initially I started out on 1600, but I wanted to see results faster so took the liberty to cut some more). It’s just been getting really hard lately. Has anyone taken a break and upped their calories to more of a basal maintenance rate (like 1800 for me probably) for a week or so to avoid diet fatigue? I’ve been reading this is a thing. I heard it helps with metabolism. I know people do cheat meals and cheat days but I feel better when I eat cleaner, I’d rather just eat a little more for a while. Many days I go hungry. Or would this undo my progress and cause the weight to start piling back on? I swear, dieting (at least for me) is so much more mental than physical. I’ve become so distrustful of my body and it’s sad.
