It doesn't prove that you are worthless. It proves that you have a mental condition as many of us here do. When was driving with my H earlier and made a mistake--when he pointed it out I totally jumped out of my skin and decided only to do 2, rather than 4 errands (may try the last 2 later). I get quite jittery too! I know I have been paranoid on a few occassions. I am just not as resilient as I was when I was younger. It happens. We are still good people. It's OK.

What have you tried to sleep? Melatonin helps and CBD or more psych drugs might. Are you going to contact your VA doctor? You should consider it from my POV. You need to get relief.
