I've often said in these forums "worry is non productive". It doesnt produce a thing for your positivity.
You can worry that you have an appointment the next day. Then you dont sleep because you are worried you will sleep in or forget your CV documents or not be dressed up well enough. All 3 things in this example is worry for zero benefit. You can have 2 alarm clocks to prevent you sleeping in, you can place your CV in the car so you dont forget it and you can select your clothing the night before....so off you go and have a good night sleep...bet you dont!!
That's because 'worry' is inground, it's part of you, like a limb. So it's extremely difficult to rid yourself of this burden.
The first and most important step is separating reality with unrealistic thoughts. When we allow out thought patterns to trod along without challenge then we have a problem. Discipline to attack unrealistic thoughts has to be there for many reasons like - the less you think unrealistically the more time you have for real thoughts. And unrealistic thoughts can cause other issues to-
Fear! In 1987 I had a big dispute at my workplace. A pain in my chest and an abnormal heart beat led to a diagnosis of heart attack. This was incorrect and after a few months it was found to be a panic attack. My therapist asked me weekly what happened during the week and I'd tell him I thought my boss would knock on my door, or my doctor wouldnt believe my fear was real or I really did have a heart attack and they got the diagnosis wrong again. Can you the reader see where I'm coming from?
The next step is relaxation. Learn it. Go to relaxation classes. Learn muscle tensioning exercises. They really work. What you would be doing is learning a task that some do naturally but for some reason you missed out. It isnt your fault but if you dont attack the issue it will be your fault. You wont find a relaxing life and that is not good. Take it from someone who knows.
The last step is prioritising. Placing things in priority allows you to tackle the hard things first then as you tackle less important things you begin to relax more. Finances is a good example. Low on funds you should be shopping for food instead you decide to get that truck load of manure for the garden. For the rest of the week until pay day you struggle with coins only in your pocket. = worry.
Worry is non productive.It doesnt produce a thing except hurt, anxiety, depression or at least assists these things.
Remove it from your life.
