Which problems are most typical for teenagers? why do most teenagers use childline

One of the typical problems for modern teenagers is that almost all of them have some sort of school problems with their classmates. Tgey can be subjected to call-ups on the part of classmates. And of course this affects their still unformed psyche. I also think that spending a lot of time in front of computer is not only a tupical but it's a global problem for children of our generation. Because spending a lot of time at the computer, they become aggressive and can not control themselves. For me the average rate is half an hour or maybe an hour. Some children have already started to drink from an early age and the most terrible use of drugs is also one of the most common problems at the moment. Government and we must definitely solve them.
