If you face serious disorders, you may consult a doctor.
I don't like too much medicines, so I will suggest you to get an alternative therapy to relax or give balance to the mental health.
Meditation is a good healer for problems like depression, anxiety, tension, loss of sleep and more.
Reiki is also a good healer which require to get help of a reiki master but allow you to get healthy after a few sessions.
Jogging, walking or visiting natural beauty places, spending time with children, elders and serving others in your spare time will also give you mental relief and satisfaction.
