I suffer from it too, I managed to train myself to do the ride to work and back home from work without too much anxiety, but anything else is hell for me... I wish I could give you encouragement but Ive been fighting this for over 10 years and im also reaching my limit... no social life, no love life, I literally have nothing to talk about outside work and the books and series I enjoy in the safety of my room... the thing that worked for me the most was a combination of meds and therapy, with those I felt brave enough to challenge myself and go outside to do different things daily and I actually got quite good, even socialized a bit, best way to erase agoraphobia is doing what you fear, but we both know just how hard that is... I send you a lot of strenght and support from my side, the fact that you are still here means a lot, I know you try hard even if other people may see a lazy person I know you are trying...
