Often during times of spiritual awakening we loose ourselves and no longer feel a sense of belonging.
This also includes a loss of faith or a change in ones religious preferences. Anger will also arise,anxiety, depression, confusion,insomnia,fear,needing more sleep, eating habits etc.
This is all quite normal during the opening of the chakras and your kundalini activating through them. Try to be mindful of your thoughts and emotions not letting them overcome you. Acknowledge your feelings but do not dwell on them too long. When you are feeling angry try breathing deeply and centering yourself.
