Lost weight then got fat again

Hey guys so about 3 years ago I I lost 35kg. But after getting into a relationship I've gained almost 20kg back 😔. I'm 5'2 now weighing 67kg. The first time I lost weight it felt so easy although I always felt like I was starving - I had self control. This time around I feel like I have absolutely no self control at all. I feel like I have worms I eat so much. Can you guys help me sort out a weightloss plan? Meal ideas. Exercise ideas. Ect. I have a gym membership and I want to make use of it *(mainly cardio tho bc I'm scared of the weightlifting area). I want to be eating 1200cal a day. Plus atleast an hour of exercise a day. I am struggling with food though. What to eat? How to stop eating.... 😔😔I feel so disgusting for letting myself go again
