I'm sorry you're hurting and struggling so much.I am wondering if it's ok if I ask a few questions.

How the heck did you drive yourself to the hospital after hurting yourself?
Why did you go to the hospital in the first place if you don't want to be safe or admitted?

I'm really not trying to sound uncaring or heartless,just trying to understand.The title of this thread is "sent home to kill myself",like you are upset about it yet you don't want anyone to help you or do anything for you.You weren't "sent" home,you discharged yourself.Were you hoping they would admit you against your will?What exactly were you wanting?

hugs
