It's about covering up and pretending your all righ when you're not. Acting as if your life is a 'paradice' when it isn't and your just bottling it up. 'one more day in paradice' basicly means 'one more day of lies'. 'nothing hurts and nothing bleeds when covers tucked in tight' implies that covering up and hiding beneth the covers makes you forget your pain. 'she slowly swallows all her fears and soothes her mind with lies' that says every thin. 'don't pretend to hold it in - let it out' is just saying stop bottling it up.
