Method to Pass Out?

[SymphonysofAgony]

I am so desperate to die. I am desperate to cause myself physical harm, so even a suicide method that can result in me being a vegetable - I don't care anymore, I'm willing to try.
HOWEVER. It is currently not possible for me to ctb, so I'm wondering if anyone knows of a way I can at least knock myself unconscious? Could I suffocate myself with a blanket for example?

hyperventilating, also i tested the night night method with my hands and felt i would have pass out if i did it longer so there's that.

Ah I'll try those, thank you for your reply! I've been interested in the night-night method myself, but wasn't sure if it could work for me due to lack of supplies. But you were able to almost achieve it, just be wrapping your hands around your neck?
