The goal in life is to be happy. Anything that is interfering with your happiness should be attended to. It is important to take care of your mental health to be able to enjoy the small things in life and be effective in the many roles you play in your family, relationship or workplace.
If when you evaluate your current state of mind you are feeling unhappy, how unhappy do you feel? Is it something that can be easily fixed, or do you need further help?
