I've given it some thought and I think I need help.
What do you need help with?
I feel like giving up on life
If you feel like life is not worth living, then it is good for you to seek help.  In this case, I would like to refer you to someone who can talk this over with you right away, as they are professionally trained for these situations.  You will feel much more confident after you talk it out.
I'm not going to. I am confused and I don't want to live.
I understand your reluctance, but it's crucial you get help as your suicidal thoughts are dangerous and you deserve to feel better. What you're feeling is temporary and there are people who are ready and able to help you get better.
