Yes and no.

There is definitely a lot of shame around self harm and a WHOLE lot of misunderstanding and judgement from people who think they know how to help.
When this behavior first started for me, I didn't tell my parents, someone else did.

I've had good years and bad years. Currently I'm in my 20s and just finished an extraordinarily difficult semester at school after returning from a year off on medical leave (for psych reasons). I am so ashamed that this behavior is still a part of my life, even though it's extremely rare for me now, only my therapist knows.

I don't know if self harm is a behavior that will ever be understood by someone who doesn't struggle with it, or is trained to help people with it.

But I do hope that the shame surrounding it will not last for ever. For you or for me.
Some battle we choose, and some battles are chosen for us.
Shame, in my opinion, is a battle worth fighting.
It is the enemy that keeps us isolated and alone.
We're not alone.

Keep fighting, my friend.
