OM SAI RAM
Hey Piya,
When you become really intolerant, that's the time to look within and calm yourself.
Find the energy within to absorb all that, which makes you angry.
Picture yourself the most violent and full of rage volcano, take your journey down the mountain, hitting rocks, trees, and killing everything in your way, including yourself. After sometime you will be tired and will look for the sea. that's when you will automatically start feeling quiet.
Feel the anger and frustration diminishing and you reaching a calm and serene stage in your mind. All will be well.
