【答案】Dear Chris，
As to how to keep psychologically healthy，more and more people around me have begun to attach importance to it.Nowadays，many students suffer from mental illness，which seriously influence on their study and daily life.
The cause of mental health problems often varies a lot from one case to another.A good number of people are suffering from heavy pressure.Others lack support and communication skills.In addition，a lot of people are ignorant of psychological knowledge about how to keep mentally fit.
In my opinion，there are a lot of ways for teenagers to deal with mental health problems and keep psychologically healthy.Firstly，find the real cause of your mental health problem and see whether you can do something about it.Secondly，learn to relax yourself and take exercises to release the pressure.Lastly，you may find it helpful to talk to your parents or friends about your problem，or seek support and advice from a psychological consultant.
I would be very glad if what I talked about above were of some help，and I am looking forward to your response.
                                                                       Yours，
                                                                         Lijin
