Will I have trouble losing weight even if I am too tired?

I'm helping the kids study for their final exams these days.

I'm on a diet at the same time, but I'm so tired.

What's even more depressing is that after an hour and a half of cardio...

I'm only eating one meal a day, but I'm not losing weight.

I've maintained this for a week, but there's been no change in my weight.

Will I have trouble losing weight even if I am stressed or tired?

I keep avoiding my body, so I'm not losing weight.

I'm wondering if I should go on a diet again after the final exams.
