I want to get to 60kgs but I'm gaining weight ...

I have been eating 1200 calories for a year but i gained 2kgs in the past week before my weight was 65. I thought I had to be in a deficit for another few weeks and id be there but now I'm gaining weight and I feel like all the work I have put in is useless. I'm 5'8 btw. I don't know what to do i feel like I'm failing even though I'm barely eating. Should I eat less, what am i supposed to do? I really want to lose this weight but I'm scared of eating more so I don't know anymore...

I track my calories properly and use a scale so I'm not miscalculating anything. I need to lose 8 kgs now and I want to lose it in 2 and 1/2 months.
