If you suffer psychologically, just wait a moment and observe, observe everything what is happening, the sounds, the colours.. and also observe that you want something. That wanting is the suffering at the same time. On a lower level that wanting is simply thought, non-functional thought to be precise. You can all it desire (for security, people, money, a house, success, etc.), fear or anger, it doesn't matter because it's the same process, the same mechanism. Desire is followed by fear like a shadow, they go together.
