Trigger warning

How bad do you have to hurt yourself for it to be self-harm? I don’t cut, I don’t do anything that hurts for more than a minute (well, normally). I hurt, but it’s not really harm. Saying that I harm feels like I’m exaggerating, and belittling those who seriously harm. So I haven’t told anyone. But it is something I do in a similar way. So is it the intended mental effect or the physical effect that matters?
