Ok, lately, ive been having difficulty breathing, especially when I lie down at night to go to bed, it sometimes happens in the day, but im short of breath, and my chest is tight, at first I thought it was asthma so I went to see my doctor about it, and he said its not asthma because im not wheezing. So I am eventually going to have a chest x-ray.

But it still worries me, I think, more like I worry, that theres something seriously wrong with me. I dont get any pain at all. My friends said its probaly the fat around my heart, which I dont doubt because I eat 5-8 bags of crisps a day, and the fats clogging up my arteries. Oh and im a 16 year old girl?

Any ideas?
