Of course we all worry about things but personally I try not to let worry overwhelm me to the exclusion of all else. Worry tends to come about when you are not in possession of all the facts.
To me extreme worry/anxiety is an unhelpful emotion, driving all sorts of speculative/negative thoughts and behaviours, and to what gain?
Having worked in the NHS for 44 years I've seen and heard about most things: been with patients whilst they have faced a devastating diagnosis, seen patients with catastrophic life changing injuries and spent time with patients who have no-one to care for them in the most basic sense.
It tends to put any worry I have into perspective. And if I do start to worry about something I try to bring it back to basics and remind myself that I have a loving family, I have hot and cold running water, I have a secure roof over my head, I have heating and light and can afford to pay my bills. I have enough food and I have assets that can be sold to raise money for me or mine if needed. I can dress and feed myself, take myself to the loo, I can walk and play and live independently.
If you can change an outcome with worry then go ahead, but if you can't then let it go and focus your energy on something else.
P.S: I'll let you into a secret. I worry a lot about a new (currently very immature) hedge that has been planted by some new homeowners near where I live. Their garden is on a corner of a busy T junction (opposite a primary school) and adjacent to a main road with no pavement. The previous homeowners used the slightly raised flat area as a veggie patch with no boundary hedge. Sight lines in both directions were good for pulling out against oncoming traffic.
Once the new hedge thickens out (and judging by the way they do not maintain the rest of the garden I suspect they may 'forget' to cut the hedge adjacent to the road) the sight lines will be obscured making it very difficult to see oncoming traffic.
So it worries me. Can I change it? Well I could put a polite letter through their letterbox and see what happens. I'm sure other users of that junction (particularly those on the school run) will also find it problematic, so it may get raised by them anyway.
My husband says 'let it go'!! if it becomes a problem we can avoid that junction and take a slightly different route out to the main road'.
