Then there’s the common interactions with rude or stupid people that most people in a better place blow off and don’t remember, but people in a state of depression absolutely do and are injured by.
I’m just an average middle aged white guy, but I’d say that at least once or thrice a year someone, usually a woman, will make some stupid comment about how I look creepy or I make them nervous just by going about my business. Usually I blow it off, but if I’m suffering a bout of anxiety or depression (yesterday was a very bad day), then that sort of stuff hits harder, gets really offensive and I react.
Hell, 30 years ago I rode up the elevator in our company parking ramp, my employee badge clearly visible on my shirt and yet some fucking idiot woman cowered in the back of the elevator staring at me with her mace in her hand. I was young and very angry about this and if she had maced me for no reason but her fear, I’d have likely beaten her within an inch of her life, but I stood there, on the other side of the elevator, kept my face looking neutral and at the door.
I could go on with these kinds of issues, but they don’t reflect on me, they reflect poorly on the people who do this sort of thing. I’m just an innocent bystander being harmed by paranoid assholes.
But if you’re some guy with the kinds of issues we’re talking about and these things happen to you, you’re likely to remember them and let them fester.
