Over eating...Help.... Urgent!!!!!!?

I am a 13 year old boy, I weigh 130 and am 5'4. Lately, I've noticed I have been eating more. Like I would have breakfast "one toast, 1/2 tbsp cream cheese'' then like 20 mins later I'm hungry again. So i got some popcorn and ate 1/4 of the bag, then i told myself i can't eat till 3:30 when it was like 12pm and so ya i didnt eat. my mom was at the doctors so she brought food,a chipotle burito (barbacoa, rice, lettuce, red sauce, and corn, i know cause i texted her what i wanted). So usually after eating that i would be really full where i can throw up but i wasnt full but i wasnt hungry either. I have had a 45 calorie popsicle since then and i need help on what can fill me up and be healthy becaue i want to lose 25 pounds. And ramedan is coming up and i want to fast for a month, and im worried i cant do it like this. am i eating bad food or is it just puberty.
