Oh wow 58, I'm so sorry for what you are going through...honestly it sounds like a doctor would be a good idea...are there any free clinics where you are?
The sad truth is that most families aren't great support networks for people in recovery...I have still not spoken to my family about it and don't see that changing. Would you consider AA? It might help you to have some face to face support.
There is a gratitude forum on SR....I find it extremely helpful when I am down to post there...a practice of gratitude can make a huge difference in ones life...even when you aren't feeling all that grateful.
Hugs.
