What household items can kill me?

I've been going through very hard times in my current household. My mother has destroyed the one thing I hold dear and I'm ready to go. I would like to know which household items can kill me while I'm sleeping. I don't want to feel the pain. I just want to get it over with. I have thought of this consequences and I don't want to hear, "Call a suicide hotline." Or, "Get counseling." I would just like an answer to this question.
