No,you must tell so that the life of your friend isn't gone. If you truly are a good friend you would tell people that can actaually help.When friend kills him or herself you will feel guilty and even if he stops being your friend for it just know that you saved him or her so the answer is false
Sometime life isn't easy but there is no point that person should give up their life. Being someone is something but losing it all won't be a solution. Me personally wouldn't tell anyone bc i would do my best to help and be there for them...
