Hey Dean...get yourself checked out (even if you have to make payments on the bill.)
Otherwise, if you want to play Russian Roulette with your life, my "common sense" advice to wifey was to make sure the Life Insurance premiums, etc were paid up.
Yeah, you can do the stuff those youngsters suggested, but until you see a DOCTOR and know exactly what you are up against....the advice is useless...
Having been there, I can honestly say, having a husband die is no joke, even worse would be if one's husband had a stroke, was regelated to a wheel-chair, or became a vegetable. You see where I am going with this?
Get yourself checked out... we care.
