Remember that your life is not your PR. You have so many blessings around, your family, your friends, your life.
Your current situation is temporary, one day your Golden email will come, it will happen.
Make the most of minutes, hours and days, because we will never know when we will run out if time.
Keep positive and trust God.
If you feel anxiety and depression are taking over please ask for help. Most of the employers have employee assistance programs, access those.
Remember that nothing will make sense nor even your PR if you are sick or in a hospital. Take care of yourself.
