I completely understand what you are dealing with here. I have been housebound not too long ago as well. My suggestion is (as Lyn said) "baby steps". The only way to recover from this horrid disorder is Exposure, not Avoidance. The more you avoid, the worse it gets. It's a self-perpetuating dragon, the more you avoid it the bigger and meaner it gets. The more you face your fears, the more likely they are to fade. My first day back to work after months of "hiding", I literally had to pick up my legs and put them out the car door, take one step at a time, concentrate on only that (it's just one step...it's just one step). Well it works, as silly as it sounds. I am not housebound anymore, although the tendencies are still there. I could easily revert to hiding at home if I let myself do it. Best wishes and (((Hugs))),
