I apologize as I know not the background. Is it running into people? Being outside? Or is there a different trigger?

For me, I actually felt safer walking in my neighbourhood in the dark when there were no people. My therapist (who even met me a few times) suggested I take my walks 30min later each week until eventually I was able to encounter being around some other people. She was also good enough to discover a 24hr grocery store so I could get out and do my groceries when the shop was nearly empty.

Do you have some sort of patio or deck or maybe a place you could put a chair outside? You could start with simply touching the chair.

Maybe too if you were to place something comforting inside the door?

Perhaps I'm just grasping at straws. I really wish I could help.
