Many problems can be caused by poor mental health. Without proper socialization, PTSD can worsen. Many people suffer from PTSD as a result of past traumatic experiences and being alone and not socializing leads to lots of worrying. Although thinking about certain things is healthy, too much or too little can lead to mental disorders. Among other things, it can cause drug addiction, depression, and suicide.  

   These are just a few examples. People respond differently to happiness and different people in their life. You can communicate and stay socially active by having a support network, a group of people that help you fulfill your life goals. Some people do not have a trusted, open, and caring person to talk to. A therapist may be needed if the situation becomes serious, which is always an option. It is important to use social media correctly, though. Fake news should be avoided at all costs. You can put yourself at risk and be stressed by fake news. Social media may cause you to lose touch with reality and what makes you happy, if you use it so much that you never speak with your family or friends. Your real-life experience is lacking.
