I'm not really sure how to start this but I think the title makes it pretty obvious. I, 18m, live with my mother and younger brothers, and for the past five-ish years she's been displaying clear behaviours of schizophrenia. Because of this I had to take on somewhat of a caretaker role for her and my siblings and consequently couldn't keep up with school and had to drop out. She has been hospitalized once before and was given medication after she assaulted a member of the public, but she threw it out almost as soon as she was discharged and no similar incidents have occurred. We stayed with our dad during that period but we don't live near him anymore because she doesn't trust him and cut contact entirely. I did try once since then to get help for her but I called the ambulance and I don't think that was the way to go because they weren't able to help her without her consent - obviously she just got mad and sent them away, now she trusts me less too.
For the past couple months we've been staying with my grandma while my mum looks for rental places but she's not very mindful of mental health issues so she's been getting mad at her but not helping in any way which has only made things worse.
I feel like I'm walking on eggshells all the time and I know I'm supposed to be the one to help her but I don't know how. Any tips? I live in Australia if that's somehow relevant. My own mental health is really drained and I've even contemplated offing myself but I know it would be cowardly to leave my brothers to deal with this.
