My dad killed himself when I was 15. I found his body after coming home from school on a sunny day excited to tell him I'd finally done well on a math test. It destroyed me emotionally. I didn't come right for 5 years and it left permanent emotional scars. It was hands down the nastiest, most brutal, awful and enduring experience I've ever had.

I beg you to reconsider. Talk to the people in your life about how you feel.

Edit: reflecting on this I feel like there is a law of conservation of pain. You can't eliminate your pain by suicide, you simply transfer it to others.
