I've felt the same way. When I was at the VA hospital there was this guy had some degenerative condition in which his immune system attacked his body. He lost most of his eyesight, was wheelchair-bound, needed someone to feed him, had months to live AND his wife left him during this. What's worse is he was only 34 years old. The man still had a good attitude, was kind to others and didn't seem down on himself or feel like he'd been dealt a bad hand.
One would think this would offer motivation to me that things aren't that bad, but nope. Still dwelling on my issues.
I mean, people are starving in other countries, willing to do whatever it takes just to survive, and here I am, a white man in a country that offers considerably more than most others, and I just feel bad for myself. So pathetic (me, not you).
