If you feel you might be suicidal, and live in the United States, I urge you to call the Suicide Hotline at 800-273-8255 or navigate to the Suicide Hotline website for a live chat and additional resources.
If it's not an emergency, but you want to know more about mental health, the National Alliance on Mental Illness (NAMI) offers information on their website and a free HELPLINE 800-950-6264.
If you do not live in the United States please seek out local resources. Here is a list of international suicide hotline phone numbers.
Let others know if you need any other guidance to people who help.
