If you can see and accept that you create your own stress according to how you are responding, you will then see that there is something you need to unlearn as well as learn.
The old response needs to be unlearned, and a new response needs to be learned.
There is part of you that is perfect and pure. It is untouched by the less than perfect characteristics you've acquired by living in a less than perfect world. It is filled with divine qualities, so is a constant state of resourcefulness and well-being. Its total absence of conflict and negativity of any sort makes this part of you a Still-Point; a deep, enriching experience of Silence. Make time to practise reaching this inner place of Silence. It will bring you untold benefit.
