I understand. I worry my head off about this kind of stuff to. I worry on a small scale and on a large scale. I even worry about worrying. I can hear the worry in your words too. It sounds like you are feeling a lot of anxiety with all this fretfulness. I can really relate. Do you have a doctor or therapist you can talk to?? Do you take meds for anxiety?? Do you employ any relaxation techniques such as meditation or mindfulness?? They're all over the internet. There are also websites that use self-help cognitive behavioral therapy to help you overcome anxiety. Anxietybc.com is one my doctor recommended to me. Distraction is a really good way to get your mind focused on something besides your worries; I try to do logic and math puzzles to get me thinking of anything but my worries, or I do something different like walk my dog. These are techniques I was taught by a psychologist. Try some of them, and see if you find them helpful. I was told to get out of where you are and into a whole new atmosphere when you are fretting as you will not fret once removed from your 'worry zone'. Good luck to you, and take care. Also, feel free to message me anytime. I'll be thinking of you.
