As a young person, you may be experiencing what all teenagers go through, puberty. Adolescence is a time of major hormone changes, leading to moodiness. Staying in this state for longer than two weeks and moving away from your norms (normal ways of being) could signify developing a well-being issue.
Next time you are feeling moody, do not judge yourself. Instead, become mindful and curious.
Are you your emotions?
Do your emotions define who you are?
You cannot fully control your thoughts and emotions, but you have the power not to let your emotions control you. Accept that emotions are part of you but do not define you. When you feel moody, zero in on what is going right in your life, even if it is something simple and ordinary.
