Suicide isn't really illegal, you can't be prosecuted for it or for attempting it. It does have some interesting corner cases. If police believe you are attempting suicide they can enter your house to stop you without a warrant. A person who attempted suicide but was stopped or saved by someone cannot sue that person for any injuries sustained during their rescue. And of course if you are considered an active threat to yourself by a qualified mental health professional you can be involuntarily admitted to a psychiatric institution.
