Помогите написать сочинение по-британскому на тему ,,Teenagers problems. How cope with

So, now I would like to talk about teenager problems. I think the main problem of the teens in our modern world is pernicious habits. Now teens start to smoke and drink and moreover show it off. Psychologists believe this behaviour appears because such children feel themself unnecessary and unloved so they full spaces it their hearts with alcohol, drugs etc. Even if I am right such teens will never admit it. Well, I can say that their showing off does not end only on drinking alcohol. We can see a lot of photos of smoking teen on the Internet. This teens need attention they have not received from their parents. It is terrible and I think we have to deal with this problem. Parents only should look after their kids and speak with them not only about good things. Problems wiil not disappear if we would just ignore their existence.
