Kelly,
I'm so sorry that you're feeling so badly. Please know you've been heard; that someone somewhere hears that pain and understands it.
If you are actively feeling that you could harm yourself, please seek help immediately to attempt to address these thoughts in a safe way. You could call your local crisis line, go to the emergency room ER, or contact the national hotline. Please let someone trained help you when you feel you don't want to help yourself, or that you can't.

We're here. We care.
