I've been at wits end a couple of times before, but I've always managed to get my act together and keep on going. This is different though, I'm in pain, my mind is spinning, I feel seasick because of the dizziness and I can barely get the most important things done durng the day. I've admited defeat and I've seen a doctor about it. The solution is of course to change the situation I'm in, but that's very difficult to do as things are right now. (My main stress factor is the fact that my husband is very ill.)
I've had to drop all the projects I've been planning to get done and is now struggling to make it through one day at the time.
