I am 15 years old and smoking for 3 years 1 cigarettes per day. Now i feel some pain in my left side of lower chest when i laugh or cough. I don't want to tell parents about that because they might know that i smoke. What causes that pain???
I have some bad marks in last 2 semester. Holiday is about 2 week. I need to learn all my lessons from beginning to have good marks in next 2 semester. Can i learn all lessons in only 2 week???
