I'm feeling suicidal and I need some help. Can you give me some advice?
What's the reason you're feeling suicidal?
I don't feel like I will ever achieve anything valuable to society in my career.
I know you feel upset about your career situation but you need to focus on the positives and not think about suicide. You can make changes so that your career is more satisfying or choose a different career that will lead you to make valuable contributions towards society. You should discuss your issues with a career councilor and they can help you make the decisions you need to.
I'm going to kill myself.
I can call someone to help you and get you back to being in a better state of mind. You don't have to do that to yourself and you need to realize how many care for you.
