I'm currently in the hospital but I really feel like discharging myself from here.
I would you want to discharge yourself from the hospital?
I see this as a waste of time. I will be back at work soon.
You should consult your doctor first. It not good for your health to make decisions for yourself. If you want to recover soon you should stay in the hospital.
I want to leave now.
I understand you want leave now, but you need to make sure you have the doctor's permission first. If you leave early you may end up right back at the hospital.
