i do understand you, and i wanna congratulate you, losing 30 kg is amazing! especially being 15 and yet so dedicated already. if you keep up that ambition you will get very far with body building, im 100% sure

however, not eating at all is really bad (altho your nutrition is not all too bad). if you lose fat and weight to quickly you might lose muscles too. but you better watch the video
6 pack abs fast part 2 by scooby. it tells you everything you need to know and i wont tell you more than scooby in this video. it tells you how to lose weight and gain muscles at the same time and also provides you with some nice ideas for healthy meals which are perfect for you.
and i know what you mean, when i started out i had the same thing. when you train your abs theyre pumped and thus look bigger and it also depends on some other factors.
try to not eat candy anymore, once in a while might be okay but especially when you wanna lose fat you should minimize the amount of candy you eat
