Barbz, there are several methods to try..different things work for different people. Other than one on one therapy, Anxiety workbooks that they sell at books stores are very helpful.
What often happens Barbz, is we start to ask or thing about a lot of what ifs and it's usually followed up with something negative.
If you were to think what if I become agoraphobic again...that is negative...then it should only be fair or better question to ask yourself, what if I never become agoraphobic again...positive thinking!
At some point to change, we must stop thinking negative. We do that because we are afraid and in return it heightens are anxiety and we worry! The less we focus on what we are afraid of, the less of a hold it has on us.
So many of us have had not just anxiety but panic as well, and if you are one of those that have, we know that each and everytime we have got through it...so we know the worst case scenario, right?....the key is to stop dwelling on what if...... followed by a negative or thinking about the worst case scenario and focus more on "we can do this" it might get uncomfortable, but it will pass like before.
What I found was, by being more positive...even though it wasn't an instant cure....far from it, but by being positive and facing my fears and trying to pay less attention to it....even though I got uncomfortable, the anxiety episodes would get shorter and shorter and less intense.
If you begin to feel anxiety or panic, just kind of roll with the way you feel and know that the less you freak out...the quicker the adrenaline stops and the sooner it goes away.
It takes time and patience to recover and even when we make progress, it can pop up again, but that is ok...stay the course and continue to replace negatives with positives and do your best to face your fears by not dwelling on them....WM
