Been 120 kg when 14yo.
Don't shift the blame on your parents you are the one who got fat.
I can bet my money on the fact that you live in a dysfunctional family.
TIPS:
0. Losing fat is a routine thus go to sleep at regular times.
1. Eat regularly (breakfast, lunch, dinner)
2. Avoid snacking.
3. Remove all simple sugars from your life.
4. If running is hard start walking ( e.g. walk to school).
5. Ask yourself why you want to get leaner.
6. Find some fat friends and work your weight together.
