In life many events happen which are out of our control, you are 60+ years old I believe, you must have made many good decisions to get to where your are now, provided for your family built a home etc,
your not being singled out by some unforseen power at work ,this difficult period will pass in time, consider confiding in your family members as they know you best ,they care and love you, if thats possible and if you can return to work maybe thats what you need to do sooner rather than later,
being at home with an illness no income , seeing your savings ebbing away, is a soul distroying experience, not many people really know whats its like,all what you worked for is now being taken away
Being self employed is no fun when work stops, its a painful experience, I know this from personal experience, the passed 4 years I lost my businees, my income, and my savings, because of Illness, I'm not blaming anyone ,I got no state benefit apart from state pension,
my wife works part time, we get by, my salvation has been my family and friends.
