Is there something wrong or is it just anxiety?

I hadn't eaten well in 3 days I pretty much binged on cookies. So the other day I had trouble breathing, was literally SHAKING and felt like I was going to pass out. My parents brought me home and filled me up with protein. I couldn't sleep all night. I feel better today EXCEPT for my breathing and it is freaking me out. All my breathing in conscious and I have to FORCE myself to breathe or I won't automatically. I feel like my lungs are giving out. My best friend moved yesterday and I'm just really anxious and depressed. My parents think I screwed my body up and I need to recooperate but the breathing thing is freaking me out. I feel like my lungs are going to give out
