When PTSD really hit, my relationship broke and I moved out on my own for a first time, not even in my native country, and everything was on me? Agoraphobia and anxiety really hit. I lived in a place where the closest groceries was in the same building down few flights of stairs and the bank was 7min walk away. Still there were times I couldn't get to the groceries and having to go to the bank for anything meant making stops every few meters to panic. Sounds rediculous and funny, but it wasn't. I was hyperventilating at any going out, when my apartment was so tiny the 'kitchen' was the hallway to the bathroom. Not nice. Living with roommates- not possible. It was a bad position to be in. Sometimes being on the bus was fine, sometimes even in a half-empty bus I had to get out before my stop. Same for groceries. I guess that was when I ate the worst because being in a store made my mind racing and foggy.
For me it was a condition of my PTSD I guess. When I got on meds and started therapy, learned DBT, did lots of healing (meditation, talking, writing, journaling, yoga, facing fears, changing the current stresses of my life) it just started improving. My skin stopped feeling like it was crawling every time I was near people, getting out started being easier, and then gradually enjoyable again. And then I found myself wanting things again- took me years, a bit more each year, but I started enjoying meeting people, working in person again, being social (I mean to an extend, still introvert by heart). So I just took it little by little. Even got to dating again, going to a pool, going to a house party with some friends and some new people! So for me, it was improving the reason I had it (PTSD) rather than working on the agoraphobia itself.
That's the best I can share.
But as you see in the comments all people seem to be different and require different things... I hope you find a solution that fits you!
Even if you always had it, I always had anxiety- we can work on things always. I believe that. Maybe it can't be removed but it can be lived with, and it can be easier than what you describe. And if you're trying baby steps- take what you think is a baby step and break it to few more steps, in my experience.
That's... my 2cents... wish I could help more.
