Hi Bella, im an Aussie too and i know how awful our emergency departments can be. I am so sorry you are feeling this way. Do you see a therapist/counsellor? Are you on prescription meds to help with your depression?
Im going to give you some numbers, and hope you stick with us here at HW as im sure you will recieve the support you need.

Im sorry we had to meet like this but im glad you woke up feeling so much more positive. I think its wise to be careful who you let in on your life as people can hurt you, even if they dont mean it. Im not sure what the situation with your brother is but it didnt sound healthy for you.
Hang in there, dont give in and dont give up- you are not alone in this,
