13 Year Old Girl Skipping Breakfast & Dinner?

I'm 13 years old and I rarely ever eat breakfast. Only sometimes on Sundays.But on weekdays. I skip breakfast and wait for lunch. I do eat dinner. But 2 days ago, I just felt like I didn't have it in me to eat dinner. I wasn't full from lunch but I also wasn't hungry. Is this bad for me? I'm not trying to lose weight, I just don't know what I'm going through. There's been a lot of drama lately. And I feel like eating is what I have control of. I understand you can faint from this. But what should I do?
