Wtf do i even do

My mom has been struggling with hallucinations for about 5 years ago. She began using meth and since then she has been struggling with hallucinations, even though she has stopped using years ago. She tells me theres people outside watching her and following her. She says she doesn’t trust anyone because she knows we are all in on it. She describes her life as a bad reality show. Usually she doesn’t talk about it, but theres times she’s feeling so bad she just lets it out. She’s extremely depressed, she hardly leaves the house, doesn’t have a job, doesn’t talk to anyone. Did I mention she’s also raising a 4 year old? I feel for her so bad, but it’s like I don’t know what to do. She’s passively suicidal, and tells me often how she feels like she’s going to be gone soon. I just try to remind her I love her, but obviously that’s not enough. She refuses any kind of professional help because she believes they’ll only lie to her (like the rest of us). I know she’s struggling and my heart breaks for her. I just don’t know.
