I am 15 years old boy. When I was 13 years old I was intelligent boy in class, but due to wrong consistency of some classmates I used to masturbation and watching pornography. Slowly I realized that it is bad habit, so I leaved this bad habit. But after few months later I have started nightfall. Now this is continue regular in 7-14 days. Due to this I am facing problems like loss of memory, weak and undeveloped body, some hair fall and concentration less. Now this year is my tenth board examination and I want to do top. Now I want to get rid from nightfall and given above problems. Please give solution or treatment or suggestion. Because it is very very important for me. Thanks.
