I'm a 17yo girl, 167cm and 50kg. I find it VERY difficult to reach at least 1000cals?

I calculated my calorie intake for simple BMR - and for just that- I need 1363cals for a person of my weight and height. HOWEVER, I'm very active and exercise every morning- squats etc, ab work outs etc. jog in the park- so that in total I exercise for a full good hour daily. I also choose to walk and take public transport- and be as active as possible for a uni student. For someone to maintain my energy levels- I'm apparently supposed to eat approximately 2338 cals a day. But I can barely get up to 1000cals and at around 700cals- I'm just grabbing anything to reach at least 1000- and I know that anything under 1000cals is bad for you- but on some days I just can't be bothered because I'm simply just so full- and don't see the point of eating. But most days I -do- try to get to 1000. I'm worried that there's something wrong with me? I eat 2 weetbix for breakfast with milk, and also a slice of toast with (for example) a thin slice of roast beef. I try to eat an apple a day, I have some chocolate- and I eat the lunch and dinner my parent's cook. But I'm always SO full- (mainly from breakfast)- that I only eat because I should, and not because I'm hungry. 2000calories to maintain myself is a very daunting number- especially when I already feel like I'm energised. I don't know if this means anything- but I'm asian and quite petite- my bones are quite thin- and I'm just "naturally" small? Help anyone? I want to know if how I'm eating now is okay for my health- or is actually detrimental...I feel fine?
 
anything under 1200 aprox is putting your body into starvation mode witch eats your lean muscle mass because it metabolize faster.. so yeah its bad for you.. i would really look at what your eating and add some snacks in there or what ever you need to do
 
I think you might be eating more than you think you are.

Weetbix with milk is probably around 250 cals
a slice of bread up to 100
Beef, probably another 100 again
Apple 50
Chocolate (say 4 squares, about 100)

Already you're at about 600 calories. Unless the meals that your parents cook you are incredibly small I would say that you're more than likely eating more that 1000 calories.
