I have a question, please.
 

They wouldn't tell your parents if you didn;t want them to know as you are legally an adult I think.
PM me if you want to talk.

like becky said they shouldn't let your parents know without your consent, they may want to get them involved as part of a plan to keep you safe but in the end it should be up to you. I dont live with my parents anymore but can really empathise with not wanting them to know.

i think it depends how much of a risk to urself u r. i am 26 and live in melbourne and havent lived at home for 10yrs but last time i went to hospital they called up my parents because i was a high risk and they have a duty of care i hope this helps xxx

I'm from the Uk so I dunno how it works in Oz but here they won't hospitalise you unless you are seriously very suicidal or a danger to others. They wouldn't tell your parents if you didn't want them too but they would generally refer you to a crisis team (if you have them in austrailia?) who visit you or ring you every day for a while. They would probably refer you for some kind of counselling as well.

Damn. I'm really scared coz my self-harm is getting more frequent and serious, but my parents react really, really badly to that kind of thing. So I'm pretty sure I need help but it has to be without them knowing. I'm terrified that I'll cut and need medical care and that if I do then they'll tell my parents.

Honey,
Unless your cuts are life threatening, I dont think theyd tell your parents because you're an adult. Unless you are suicidal, I dont think that they would tell.
You know where I am if you want to talk.
