I appreciate the Patrick Henry reference as I am a native Virginian, but my personal resolve has diminished to the point of no return.
Well, I'm sorry to hear that. Do you have children? If grown, do your children have children? Does anyone you care about have children?
If so, I suggest you find some grit, because if you what you believe is true, it's going to be hard sledding. The people who care about you are counting on you. And in the end, when it's time to look at what your life has been, how would you want it to be written? Stay healthy, eat well, get some sleep, be prepared and teach your family how to survive. If you think you're depressed, find a way to get it treated so you can be of use to your family and your own survival. Find a way to serve someone outside your own head - seriously, that will focus and motivate you.
Good luck.
