Ok, I'm 12 years old and I haven't got anyone in the family who smokes in the house ever. But I have got a few people who smoke at school and on numerous occasions I have breathed it in by mistake. I have asthma, and often suffer from bad chest infections.

But this time, I have a chest infection worst than the others. I brushed my teeth and all that came out was blood, I'm really wheezy when I breath, and most importantly I feel as if I'm often tired early.

I'm scared and really want help.
