Hi hollygirl33,
I know exactly how you feel. Actually, I was just about to post something quite similar. Everyday seems to be like a fight for me too. And because of recent health problems I am also always thinking of my death and my families death.
However, whenever I feel like this (anxiety) I always try to talk positive to myself. My internal conversation goes something like this: Why are you anxious, you're healthy, your family is healthy, you have good frienRAB who are there to support you, a great job, etc...stop being stupid...there are people who are worse out there in the world. It's all in your head. You made it through yesterday and you'll make it through today and tomorrow. You'll be fine etc. Then I find something to pre-occupy myself with or I call a friend.
Hope this helps....
