To be furious about what MIL said?

[irusyaus]

Teen DS struggles with his mental health quite a bit, he's been put on new anti depressants but they've not started to work yet.

DS told me this evening he didn't feel safe due to suicidal thoughts, DP suggested A&E which I didn't think would help DS as it hasn't in the past so I went with him to his room and sat with him until he fell asleep.

MIL is staying with us and she told me DP was being ridiculous for suggesting A&E, and that if DS wants to die we should let him as apparently we're making things worse for him by trying to keep him safe.

AIBU to be furious?

Vile vile woman.
Your husband is absolutely right though, your son should attend a&e for a mental health act assessment.

She can do one…
suggest to your son he speaks to someone who can help. Kooth are very good when young people need someone to talk to and it can be via text which a lot prefer.
Be strong my lovely, sending you a hug

She needs to be kept away from your son. She is dangerous for him. She would actually prefer her grandson to die than get help for his mental health?
