I go through periods of becoming pretty agoraphobic. I am no longer totally housebound, I went through a period some years ago where I only went out for dr. appts. (and with my husband accompanying me, plus I had to take extra meds). I'd say keep working with the therapist, definitely try meds because being housebound is pretty serious, and when you get to the point where you try and expand your boundaries and go out little by little, do it. Go out every chance you get, every time you feel like you can, and even when you can't. It may take you and your therapist a little while to get to that point, but when you do, keep practicing. As for now, try and at least move around the house as much as possible, maybe going in the yard or to the mailbox, that sort of thing. I know I was so bad at one time that I hated leaving my bedroom. Take care and you can overcome this, it isn't easy and you may have some setbacks (I still have some years later, but I am now able to travel and drive by myself and go out alone, even though those things sometimes frighten me if I'm going through a bad period). Keep posting.
