It happens that the meaning of life is lost to some tragedy. If you are in a difficult situation, disappointed or experienced real grief, in moments of despair, you can make a lot of mistakes. So when you feel that life is meaningless, you need to first calm down.
Relief from strong negative emotions. Release accumulated aggression in the gym, or phrases on paper. Your goal is to regain your ability to think clearly. Try to find a calm, steady mood. You need it to understand myself and to find new values.
If you think that life has lost all meaning, so you mean he was. Define what was the main purpose of your existence. Then think about why you believe that this lost value: you have made some mistake or just disappointed in her?
When the meaning of life is lost because of your behavior, for example, you broke up with your loved one, and more peace to you is not nice, you need to draw conclusions for the future to adjust their own behavior in the future. Then you need to look for something that will replace your loss.
In that case, if you are disappointed in their ideals, you need to look for a new one. It is important not to blame yourself for faults and mistakes.
Think about how do you define the concept of "meaning of life". Maybe you consider it too globally, while purpose in life may be simple human happiness.
Perhaps life for you has lost its meaning due to the fact that there was no time to reflect on your real values. Relax, meditate, read, give yourself time to rethink its existence and absorb new information.
This pause sometimes helps to take a fresh look at the world. If you have the opportunity at some time to retire and go to another country to start a new spiritual journey, use this as a chance to turn his life around.
Maybe you just got bored. When a person has no special problems and there is no personal development, he can begin to stew in their own juice. The result is a feeling that life has lost all meaning. If it's your story, do new things.
Think it may be time for drastic changes such as the creation of his family.
Let your life yet nothing happens. Hyped up themselves. Learn something new, do some charity, give time and attention to those who need it.
