I was the same last year, but it wasn’t just leaving the house, other anxiétés too. My GP was brilliant and I was given some drugs to help, non addictive and a low dose, I also had counselling, CBT, with small weekly targets (this was done over Zoom video). I’m not quite back, off the tablets, but they are there if I have a need, every day improves and the slow reintroduction of our normality suits me. Every one is different, take some of the advice here, I wish you the very best of luck and no, you are definitely not the only one x
