I just don't know anymore

Lay me down...make me believe tonight. Tell me that what we have is worth the fight. Cuz baby to be honest the end is in dead sight. I don't want to do this without you, when you're gone it's like I see no light. Things have to change I won't keep living with lies. I'm tired of falling asleep to the sound of my muffled cries. Tired of living in doubt questioning if you really care about our life. It used to be "we" now all I hear is "you and I". It isn't right. It isn't fair. We should never wonder if the other cares. Turning small paper cuts into detrimental tears. Both keeping wondering "why weren't you there?". I'm afraid that it's possible we are just beyond repair. How can I fix us when everyday I'm filled with such despair?
