Hi, you have mentioned here about family issues, maybe some major change occurred which give you so much of stress. You have to learn stress management techniques which includes breathing exercise, relaxation techniques. Don't think so much about the past you have to understand that past is gone now live in present and enjoy every bit of life. Don't create sadness in your environment if you are not happy, people who live in your immediate environment are also affected by your behavior. Because of stress your health is also suffered a lot. Stop thinking and remember you can't change anybody but you can change only yourself. Control your anger with breathing exercises. Remember this anger only spoiled your physical health.
