Hello ForeverLonelyGirl: Thank you for posting with regard to this important concern. Yes, it certainly is tragic when anyone has to choose between health care & food & safe housing... But it seems like this is the way it is nowadays in the U.S. & I suspect in many other countries where one would not expect it.
You pose an interesting question regarding the suicide rate among older adults as it relates to poverty. I don't recall seeing any statistics of this sort. However, they may be out there. I spend a certain amount of time on the topic of suicide prevention. So, if I come across any statistics on this relationship, I'll try to remember to post them here on PC.
Best wishes...
