Fair block?

I don't care I'm just asking: Blocked by a self harmer because I said hurt the person who hurts you instead of yourself.

I self harmed as a teen till one day I thoutght f this.

I still get thoughts of self harm but before I harm myself I go after the fucker who said or did stuff to make me feel shit and I don't self harm.

So I don't get how it's "bad advice" when it worked for me. BUT was I blocked fairly, is it insensitive or offensive to say this?
