Hi and welcome!
Just along the agoraphobia lines, you sound like you’ve caught the issue quickly, which is great news!
For me, the day I found it too difficult to get down the stairs of my apartment complex was the turning point. I decided that I could either be agoraphobic for a reeeeally long time, or I could start to just beat it, bit by bit. My first goal was getting to the letterbox. As terrifyingly as it was? It wasn’t as bad as the thought of being housebound for the rest lf my life. So each day, I did trips to the letterbox and back. And notched each one up as a success.
When I could tolerate (ie. didn’t wait till it was comfortable, just till I could safely get there and back) that? I went as far as the next building over. And gradually just stepped it up, in small increments, from there.
Doesn’t sound like much of a magical healing method, but actually, it’s what I needed to do. Took a lot of patience, a lot of self compassion, a lot of dedication, and a whole tonne of foing stuff that terrified me. But agoraphobia? Doesn’t go away. And the choice is to confront it, or let it become completely disabling.
So, pick what you can handle. If that’s stepping outside the front door and not going a step further? That’s where you start. That’s what you do, every day, till you can go further, and further. That’s progress. Don’t let it beat you - you can definitely recover your confidence getting out and about again, it’s just gonna take some time:)
