Of course. Self harming is never a good thing. But doing it for attention is even worse.
Then why do you care if they care or not? It doesn't make any sense.
Not really because don't know you to well.
Just do something that'll be good for you.
I know where there is a really nice high bridge close by
if you self harm that is your business why you think you need to do so
personally think you need help ! or just typing this to create drama
Find a more constructive hobby, be creative, you'll attract people's attention, not their pity.
I'm not an evil person but questions like these are tedious, it screams attention seeking just to gain reactions for self-gratification.
