Yeah, it is often those combinations of stressors that are so disabling. When I got sick, I had also lost my wife to mental illness (her medication stopped working) and she was my sole and maybe last source of real social interaction. The fact that I loved her weighs heavily, but I have become used to having things ripped from me.
Sometimes it is difficult to know whether to apply patience or persistence. To advance, or retreat.
I was an excellent runner and had formed my life around my training (including nutrition). Then it just exploded in my face. (scratches chin). Now, I am back to being the lazy, unaccomplished person that I thought I would never have to be again.
