You change your vote based on people killing themselves? Like if you are pro-choice and a pro-life person killed themselves, you would change your mind? Do you look up stats on the number of people on both sides who kill themselves and compare them? Do you think suicidal people are a good basis for a system of government?
If you do any of those things, you are not a normal voter. Voters do not care about that at all. It grabs attention, but just talking to your friend about who you’re voting for is much more persuasive. If you kill yourself people rightfully think you have mental issues.
