How can I injure my self to end up in hospital.

After my failed suicide attempt 2 years ago I felt so safe in the hospital. And I want to feel that again. But this time I have more hope for my future and don’t want to actually die. I’m not afraid of pain but I don’t want a severe permanent injury, like ending up paralysed or some shit. I’m just so desperate to get help for how bad I feel and I feel like this is what I need to do to shock people into seeing the extent of how bad it is. Because I’ve tried everything and I’ve gotten no where. No one has helped me. Don’t try to comfort me I don’t care. Don’t tell me this is stupid and not to hurt myself. I’m aware that it’s ridiculous. I want serious answers on how to get into the hospital.
