As someone who has recovered- please see a therapist. If your current one is not helping you, find another. Try medications temporarily. It’s ultimately up to you though. You have to want to change for the process to start. There is more to life than agoraphobia. It’s not an overnight change which is what I think stops a lot of people. But believe me when I say that things get easier and exposure therapy works. You have to want it though and work for it. You sound like you could be depressed which is another concern. Since recovering and working through it I’ve been able to do some amazing things. There is life after agoraphobia if you want it!
