Inform the nurses not to let anyone near your room without asking YOU first. Dont be afraid to disappoint people by politely declining any visits you dont want. And if they come round after you get out of hospital, keep the screen door locked so when they knock and your not wanting visitors, just open the door and say "Thanks for stopping by but you should have called. Nows not a good time for a visit but if you call me tomorrow we can organise a time. Thanks!"
