Ds is an autistic young adult and is depressed and expressing suicidal thoughts. He's under the GP and is on medication. We've removed any potentially harmful things and he's not being left alone in the house. He doesn't really go out. He is depressed over a particular thing, but it's not something that can be resolved and he has to come to terms with it. It's not a bereavement or anything like that.
Is there anything I should be doing? Me and dh are sensible and pragmatic, but dh's best friend killed himself a few years ago and we're obviously very worried even though we can't realistically prevent someone if they're that determined. I'm really scared. Does anyone have any experience or advice?
