I try to control it also ... I just cant . I am new to this as well .. well to the reality of everything at least. I too get overwhelmed at stress, but I completley shut down and do nothing. This affects my life in a very negative way . I cant make decisions , and would rather just live in the moment rather than deal with the stress of tomorrow, But I know my world is crumbling soon then extreme anxiety takes over and im like a tiger backed in a corner. If one negative thing happens, its like all is lost... I am a very "all or nothing" person ... there is no gray area. Its either a great day or my whole life is ruined. But latley , I hve been able to take a deep breath and re acess the situation , if you will .... It helps some, to try and see another perspective, it is difficult .. but it can be done.
