Bob, your response to the new tower is well within the types of changes that others have noticed. All radio emissions have the effect of being a stressor, which the US VA researchers Becker, MD and Marino reported in the early 1970s. On military bases getting new high power, high frequency transmitters, residents of base housing showed elevated cortisol levels and other markers of stress. Of course the military and telecom response to this was predictable. Marino at LSU, ran the definative study proving that Electrical Sensitivity is real, physiological, and that effects of EMFs can further be detected via special QEEG even in those not consciously aware of it; other studies have shown profound brain effects from brief cell phone use, but there is big money in cellular communications.
Those with brain inflammation from autoimmune, toxics, or head injury are often accutely aware of effects. Recent evaluations of those self reporting electrical sensitivity consistently show via FMRI and SPECT scans brain damage much like that of a closed head injury.
Your own home wiring and wireless use is also often a contributor, so I encourage those without OCD or panic disorders to get the appropriate meters and see if major improvements can be made there. Often, the new cell tower is just the tipping point, and the underlying culprit is the EMI radiating 24/7 from the home wiring, as well as magnetic fields from wiring and grounding problems. Both are readily correctable with some time and effort but very little expense.
Shielding of the home or at least portions of the home is possible but is much more of a technical project and expense. If done well it can have the effect of moving you 5 miles or more away from the tower. Avoid the use of expensive shielding materials such as conductive paints, and instead use things like breathable foil barriers, wire mesh, or aluminum foil. Many people have been fleeced and spent tens of thousands and accomplished such a small improvement as to be unnoticeable. My own home was built as an experiment to see what could be accomplished re: shielding of a home on a small budget. The house has been tested and provides -110 dB of shielding at 2.4Ghz. This is limited by the leaky front door, and would otherwise be 120dB. I have "overscreens" of 47 thread per inch stainless steel wire mesh over all my windows. Materials plus labor for the shelding added only about $10K to the cost, as I was already planning on using a foil laminate system over drywall which I had developed for those with severe chemical sensitivity.
I can send you an article I wrote over 20 years ago on practical, hands on home mitigation if you'll send me PM with your email address. I'm happy to help those who are willing to take the bull by the horns, learn and do for themselves. For many, the whole notion of unseen forces (radio waves, radiated EMI, magetic fields) is so disturbing that they are afraid to do anything or lapse into denial. (I was in the latter group myself.)
For normal folks without severe electrical sensitivity, Cornet makes a single combined broadband RF, ELF magnetic and E-field meter (ED-88T) which is adequate along with an AM radio- the old Radio Shack 12-467 or Sony ICF-S10MK2. Learning to use the AM radio as a poor man's near field sniffer for detecting and locating home wiring EMI is especially important; in less than an hour you can both find and identify offending sources in the home by simply holding the AM radio as you switch off circuit breakers at the main panel. Often the fix is as simple as unplugging something unless in use; for example I have found many electrical stoves have such unbelievably bad quality switching power supplies that the entire home wiring is radiating and can be heard via AM radio within 6 of any wires in the wall, ceilings, and floors. Adding a switch to turn off this portion needed only for the oven solves the problem, as the burners do not require it to be on at all. It only needs to be on for oven use.
I am very glad to help those who are trying to learn about this, and reduce the unnecessary health stress of their home electrical system on themselves and family members. It is the cheapest health insurance you can ever buy. Most problems are readily correctable!!!
Specifically for depression, I'd suspect that endocrine disruption is happening- your autonomic system is being affected. Besides fixing the home situation to dramatically lower your daily EMF exposure, I'd suggest getting free T3 and reverse T2 thyroid tests done, as well as 4x a day saliva cortisol levels, and for men, testosterone. These are all things that can profoundly affect cognition, energy, depression and/or anxiety, and are again are something that can be corrected via supplements and/or hormone replacement. Correcting the thyroid and cortisol problem can restore you dramatically.
Assessing the home situation via meter is always the starting point. Without any meter, step one is to make sure the head of your bed isn't on the same wall as a power meter, and that you don't have wireless on in the home at night, and you don't have a plug powered clock/radio on your bedside table. Meters are critical- you can't know what needs doing or if you've got it corrected without measurement.
Best Wishes,
Bruce
PS- Your distance from the tower is alarming and depending on the antennae orientation you could be in a very high level situation. If it has only just been installed in the last week, you may find that the accute symptoms will subside IF you and your wife are still sleeping OK. If it has been months, uh oh. Depression is a very serious thing, and as Glort suggested, taking a holiday from the home might be very helpful in sorting things out. But please get a meter, as often unseen WIFI transmitters can cause microwave levels higher than the tower! For those who have developed severe electrical sensitivity, getting away from EMFs can be a serious difficulty.
