You sound like a beautiful, compassionate person. Meditation is the best, most effective means to overcome intense and destructive emotions. I meditate on complete emptiness. Because my life is intensely emotional it feels good to go completely quiet and feel that anger, fear or pain break away from my mind and leave me with the stillness I find peaceful. The more I need the meditation, the harder it is to reach that quiet place. When I'm in the 'thick of the storm' as it were, I imagine a mirror ball around me reflecting back the negative environment I'm in so that it never touches me. Good luck.
