Will he die ? Please help . Suicide attempt?

I'm pretty informed about suicide, made a few attempts myself. Never heard of using vinegar, though. Aspirin is a bit unusual too. Maybe he had the worst headache ever and just wanted to relieve the pain.

Straight up, you can't help him. He needs professional help. It's one thing to be depressed, another altogether to have bipolar disorder. Think of it like a physical illness that affects behavior. That means he needs qualified doctors to diagnose and treat his illness.

If he was just depressed, I'd have a whole other shpeal for you, cause I'm very familiar with that topic, like about how to be supportive and stuff.

But this guy has an illness and needs a professional who can prescribe the appropriate medication for a serious disease.

All you can really do is be a shoulder for your girlfriend. If/when her brother pulls through, be his friend without applying any pressure. Personal experience tells me anyone suffering psychologically or emotionally doesn't benefit from pressure or uninformed advice. It'll just add to the stress and manifest as anger or hopelessness due to the belief that no one will ever really understand.

Let the doctors do their thing. They went to school for many years and lost lots of sleep as young adults so they can learn how to help people who are sick.
