Sassparella, you have given a lot of very good advice to a lot of people on these boards. What is stopping you applying that advice to your own situation? What makes you read someone else's (perhaps very similar) story and think "Oh well that's anxiety, you're fine" but for yourself it's only doom and gloom?
From your posts it sounds as though you're unhappy or dissatisfied with a few areas of your life right now. You're absolutely right that too much time can cause this condition to get a whole lot worse. Thinking positively however, you also have a lot of time to plan and act on your recovery.
I firmly believe that big changes come from a lot of small steps. I know that whenever I've been in a place where I find myself very unhappy with where life is headed, it's only by setting small and achievable goals that I turn things around.
Start with a 3-column list. Write down everything that you love about yourself and your life, everything that you don't, and what things you want to change. Pick the most important thing for you on your "want to change" list and start to think about how you might go about it. Maybe you would like to be busier during the day? Even if finding work is a problem, there must be somewhere in your community where you could volunteer for a day or two each week? Or perhaps some social gathering you would enjoy? Little by little keep working on your list, and I think you would be amazed of the results.
I don't mean to be presumptuous of your life as I don't know you personally of course, just speaking from my own experiences and what's worked for me. I know that when I've been in the darkest times with my HA, it's typically been in a spot where life has not been good for me either. Dealing with the problems in my life just made my HA fears sort of disappear for the most part. Puts everything back into perspective.
