Hi Firehawkocean. We put security bars on our windows and screen doors many years ago when we bought the house. It keeps things secure whether we're home, or away on vacation. Of course now the quality ones are likely to be an expensive project. We also have a large gun safe that is bolted to the floor to keep any valuable items in...so that gives some peace of mind.
Magnesium is considered nature's "chill pill". I would take a magnesium citrate supplement morning and night if I were you. Also a B-50 daily would be good. You can use magnesium oil topically if desired, and take a weekly 1/2 hour long, Epsom salt bath.
Ashwagandha is an herb recommended by Dr. Weil for depression, he said he successfully treated his with it. It also addresses stress.
Light can be very good to use in the home. If there's a room in particular, you can work on the lighting arrangements there for a start. Trim any outside trees that may be blocking the sun/light. You don't need fancy expensive SAD lights, I think any natural lighting bulb would be good.
Another thing you can do is brighten things up around the home, put some orange and yellow colors in the house, and maybe a few plants.
You can never be too careful to protect your home or your children, but try to stay realistic about it. Honestly, it doesn't matter if you're in a good neighborhood, those are usually the ones targeted by thieves from other areas.
Has your children or neighbors mentioned anything to you about your putting up the stickers, etc? If they have, I would carefully consider and weigh what they are saying.
Here's a few thread that may have useful info for you. Good luck, and let us know how things are going.
